Sweatpants legs cut off while making sweatpants shorts make great hats, but they can be rather thin for really cold winter days. However, because sweatpants legs come in pairs, both legs can be used to make a thick sweatpants leg hat. This guide will detail how to make a double layered sweatpants leg hat.
Take the sweatpants leg and stick it over your head. A good sweatpants leg will fit comfortably, but not be too loose. Pull the sweatpants leg down until it fits comfortably. If it does, those legs are good for making into a hat.
Take the other leg and stick it inside the first leg. Decide what texture you want for the inside of the hat. If you prefer the fuzzy inside of the sweatpants, put the leg inside the other leg with both legs right side in. The inside will show when folding the hat to shape. If you prefer the feel of the outside of the sweatpants material, turn the sweatpants leg inside out before inserting into the other leg. Hats made this way will be uniform in cloth texture when folded up. Put the double pants leg on and measure the point where the hat is comfortable and snug. Spread out the double pants leg and smooth out any wrinkles. Cut across the material, first in a straight line just above the mark, then cut off the corners. Cut the corners in a rounded shape rather than triangular, starting just past the middle on either side.
Pin the cut top of the hat together and put the hat on to determine how long you need the hat to be. Pull the cloth down, then fold it out at the desired angle. Mark about four inches from the fold and cut off the excess material on a line parallel to the fold. You now have a hat that is cut to the desired angle of a hat, only four inches too long, in order to allow for folding.
It is time to invert the hat. Take the hat apart and turn both pants legs inside out, then put them back together. You want it so that both the inner side and the outside of the hat are now sandwiched in the middle, and the sides that will be hidden inside the hat are visible. For a hat that has the fuzzy inner lining, you want the outer piece to be fuzzy and the inside piece to be smooth. For a hat that will have the smooth outer side of the sweatpants material for the inside, you want both pieces to be fuzzy side out and the smooth sides touching each other inside the hat. Sew around the entire hat, sewing the two layers of cloth together. Do not close up the opening by sewing all four layers! It is time to invert the hat. Grab the outer layer at the cut top end and pull it off the other layer to make a long tube of cloth. Reach inside the end of the tube you just pulled, grab the other end of the tube, and pull it inside until it lines up with the first end. You have now sewn up the end of the hat, leaving no visible stitching!
Turn the hat inside out and sew together all four cut layers of the top of the hat. Unlike last step, you will not be spreading out the hat and inverting the layers, merely turning it inside out like a normal hat. Turn the hat back right side out and wear. Fold the cloth up about two inches, then fold over again. Your double-layered sweatpants leg hat is complete. You now have an insulated hat for keeping warm on the coldest days, free of charge.
