It's the season for holiday giving, so you are probably looking for the perfect gift for each of your loved ones. But what should you get your sister in law?

Sisters in law are hard to shop for. They are part of your intimate family, but you haven't known them as long as your blood relatives.

The key is to look for something useful and thoughtful. If possible, draw inspiration from a common interest.

If you need some help coming up with ideas, keep reading. The following are fifteen gifts for sister in law that she will love. Once you’re done reading don’t forget to also check out our gifts for pet lovers, especially if she is one as well!

Is your sister in law a pet mom? Then think about getting her a personalized pet mask.

These days, you have to mask up to go pretty much anywhere. But that doesn't mean you should be confined to a boring surgical mask. Send in a photo of your sister in law's dog or cat to get it screen printed on a custom face covering.

She will love the opportunity to show off her fuzzy friend, while also being safe and responsible while going out. This gift is not only useful but reflects sentimental value. A very thoughtful gift on your part.

Soap is a good gift because everyone uses it. But when shopping for themselves, most people won't opt for luxurious bars.

Treat your sister in law to some handcrafted soaps that are reminiscent of her favorite wine. She'll feel pampered and relaxed when using these decadent soaps.

Want to take this gift to the next level? Pair the soap with a corresponding bottle of wine. If your sister in law is a wine lover, she will feel as though she has struck gold when she opens your gift.

Macrame plant holders are a trending way to display plants and green life. You can select a simple woven design or one that incorporates flourishes like beads.

Buying home accents can be tricky because everyone's style is different. But a macrame plant holder will look great in almost anyone's home or apartment. She will love this gift, especially if she has a green thumb.

If she isn't really plant savvy, go ahead and buy a plant to sit in the macrame holder. We recommend a succulent or something that doesn't require a lot of attention.

If your sister in law is a born crafter, don't buy her the finished product. Buy her a macrame kit and let her make her own. She will love acquiring a new skill and some home plant decor to boot.

This is a great gift because she will be able to hold onto it for years to come.

Is your sister in law addicted to her morning latte? Give her the gift of delicious home-brewed coffee this holiday season.

A coffee sample kit can contain a mix of different roasts from her favorite coffee shop. Or, you could buy one that includes a selection of different brands. That way, she can sample her way through the market without putting stress on her wallet.

Other great espresso-themed Christmas gifts for sister in law include a coffee subscription for the following year. This is the gift that keeps on giving. Each month, she'll receive a different bag of coffee to try out.

If she loves coffee, she will adore this gift. If you get her a subscription and aren't sure what to put under the tree, wrap a cute coffee mug. When she opens it, you can explain the nature of your gift.

Here's another hint: if she's not so into coffee, you can buy a similar gift that focuses on tea.

Or, if you want to be really holiday-specific, get her a hot chocolate set. Complete it with marshmallows and a seasonal spice mix.

Buying clothing for people is hard. It's almost impossible to tell what will fit someone before they try it on. So you either need to buy items with a very flexible return policy, or you should select things that will fit anyone.

You know what that means: socks. A cute pair of socks is a very flexible gift.

But make sure they are socks worthy of your sister in law. If she has a pet that she simply adores, then personalize some socks with a picture of her pet on them. She'll love these so much, she's likely to put them on as soon as she opens them.

Cute pet socks are a personalized gift that she will wear for years.

Hygiene items are tricky gifts, and it's hard to pick out make-up for someone else. But it is hard to go wrong with a spa kit.

A spa kit is less about the items themselves, and more about the invitation to treat themselves. A good spa kit for your sister in law may include:

• Bath bombs
• Body scrubs
• Body lotions
• Face masks
• Eye masks
• Nail files
• Nail polish
• Hand creams

And much more. You can buy a pre-assembled kit or put one together yourself.

Sometimes, it's fun to follow a scent/flavor theme, like citrus or peppermint.

A notepad is a practical gift. Your sister in law will use it for making to-do lists and grocery shopping lists. She can use it to write down ideas or inspirations.

And there's no reason she should have to write those things down on sticky notes or scratch paper. Order some personalized stationery or a notepad so she can take notes in style.

You can personalize a notepad with a shared interest or hobby, or you can have her notepad monogrammed with her name or initials.

This is also a great gift if she is in school or has to take notes for her job. She'll be proud to set her personalized notepad on her desk while she is working.

When you give her this gift, write your Christmas card on the top piece of paper. She'll hang onto this personalized note for years to come.

Kitchen towels are a great gift that you can get creative with. You can find kitchen towels that come in any number of cute designs.

They can be humorous, quirky, or just beautiful linens. A common theme for kitchen towels is vegetable puns. If your sister in law loves to cook, this is a good gift choice.

Fold these towels into rectangles and wrap the set together with a bow. She will love finding these under the tree.

Is your sister in law a free spirit who loves to travel? Gift her a scratch-off world map this holiday season.

Scratch-off maps are covered in foil. When you visit a new place, you scratch off the foil to show that you've been there. Your sister in law will love getting the chance to visually record her adventures.

What's more, you can buy her a glass frame so that she can display her travels in her home. These world maps make great wall hangings.

And if you and your sister in law like to travel together, this map can be a great way for you to see where you've been. It can also help you plan your next adventures.

Wouldn't your sister in law love to read a book that stars her very own furry friend? Well, it's possible. You can order a personalized picture book that features her cat or dog.

Your sister in law will be thrilled. This will likely become her favorite coffee table book. This gift is highly personalized and shows that you care.

You can pair this gift with a three-legged book stand as they have at libraries and bookstores for displaying top sellers. Let's be honest, your sister in law won't want to let this one hide on the shelf. She's going to want to display it.

This is a good gift for runners, nurses, food industry workers, or anyone else who is on their feet a lot. Your sister in law will appreciate the chance to relax with this healing foot peel.

A foot peel helps renew the skin of the feet, allowing your sister in law to feel refreshed and restored. Pair the foot peel with some nice body lotion and nail polish to make this the most luxurious thing under the tree this year.

We've all had fun putting together refrigerator magnets to form random sentences. But consider getting a themed set for your sister in law.

What are her interests or hobbies? Does she have any favorite television shows? Buy a set of magnets that reflects this interest and she will love displaying them on her fridge.

Likely, her friends are into the same things. When they see the magnets on her fridge, she'll have you to thank for creating hours of refrigerator fun.

A cocktail kit is a great gift for anyone who loves craft beverages. What is your sister in law's favorite cocktail? Buy her a kit that will help her make it at home.

A cocktail kit usually comes with measured out liquor, soda water, and any other ingredients in the cocktail. They also include classy garnishes and a recipe card to make assembly easy.

Cocktail kits usually come with enough ingredients to make two or three cocktails. If you are lucky, maybe she'll invite you over for a happy hour.

A great pairing with this gift would be a custom cocktail glass or set of glasses. That way, she can drink her craft beverage in style.

Adult coloring books have been all the rage this year. They are relaxing and can help reduce stress levels. If your sister in law is a fan of relaxing home hobbies, this is guaranteed to be a winner.

Select a coloring book based on her hobbies and interests. And to really make it a nice gift, buy her a set of pens or markers that she can use to do her coloring.

If a coloring book isn't her style, paint by numbers is also making a comeback for adults. These are fun and easy ways to be creative. It's even something that you and your sister in law can do together.

'Tis the season to cuddle up on the couch and watch Christmas movies. And that makes a cozy throw blanket the perfect gift.

Choose a design that matches her style, and she will probably keep it out on display. To go above and beyond, you can even have it monogrammed with her initials or a special holiday message. You can also add her pets to blankets as well!

Want to become her favorite in-law? Buy a throw blanket with armholes. She'll be so cozy on the couch she won't want to share this blanket with anyone.

You can stop your search for the perfect gifts for sister in law. She will love anything on this list.

Remember, the key is to look for something useful and then personalize it. She will be impressed with your thoughtfulness. It's likely that she'll use most of these gifts for years to come.
