How to create the ultimate ugly holiday sweaters

— -- It's the end of the year, which means time to break out the mittens, hats and, of course, your ugliest and tackiest holiday sweaters.

DIY guru Brit Morin, the founder and CEO of Brit + Co, shared her top tips and tricks with "Good Morning America" for how to create the ultimate ugly holiday sweater. Equal parts creative and tacky, these sweater hacks will for sure win you that trophy in any ugly Christmas sweater contest.

Morin also shared some tips for hosting a festive holiday party, featuring cocktails served in ornament cups and a DIY Christmas lights garland.

Snow globe sweater

Morin's first hack is turning your sweater into a snow globe. To start off, use felt and cotton balls to cut out a Christmas trees and make a snowy landscape.

Next, use hot glue to attach your scene to the front of your sweater.

Now here comes the fun part: Use a clear plastic takeout salad container to create the snow globe bubble. We found these on Amazon, but you could just as easily hit up your local lunch spot to see if they have an extra you can have. Fill the container with fake snow, and hot glue over the wintry scene and onto the sweater.

Finish off the look with snowflakes all around the snow globe because, in the world of tacky sweaters, the more doodads, the better.

Pregnant snow-woman sweater dress

Mamas to be, this one’s for you, and it is so easy to make. This pregnant snow-woman is actually made from a sweater dress, felt and a scarf from your closet. All you need to do is cut out one orange triangle for the nose and a few black circles from felt and use hot glue to attach the eyes, nose, mouth and snowman buttons in place.

Tie your scarf right above your pregnant belly to to create those snowman curves and you've got yourself the perfect ugly sweater for you and your baby bump.

The ultimate group sweater Christmas scene

What kind of holiday would it be if you didn't have friends by your side? This ugly sweater is actually a group activity. Grab your besties and make four sweaters that blend into each other.

Morin modeled her group after Grandma's house -- filled with tacky wallpaper, old couches and tons of presents.

There are two things we love about these sweaters: One, each sweater can still be ugly on its own; and two, these sweaters light up!

Head to your local hardware store to purchase battery powered LED lights. Cut a tiny hole in your sweater to string them through the front, leaving the battery pack on the inside of the sweater, and then hot glue in place. If we were voting, this group sweater is a shoo-in for first place in the Christmas sweater contest of our dreams.

Holiday Sweater Party Decor

The party doesn't stop at sweaters, make sure to continue the festive theme into your decor.

Christmas ornament cocktails

What's a party without a cocktail, or a mocktail?

Use round plastic ornaments as cups for this ugly sweater gathering. Remove the piece of the ornament and hot glue a napkin ring to the bottom side. Pour your favorite, boozy or non-boozy beverage inside and top off with a straw. We filled these ornament cocktails with cotton candy and then topped off with sparkling water, or if you are feeling more festive you can top off with champagne.

Christmas light bulb garland

Now we never want to forget about decor!

Use balloons and black paper cups to create a light bulb garland. All you will need to do is blow up balloons and tie them to a black ribbon. Cut a slit in the paper cups and slide around ribbon and have it sit on the top of the balloon. These are the perfect quirky and oversized ornaments you will want for your epic ugly sweater party.
