Thermal undershirts can be made into sleeveless undershirts or made into “A-shirt” tanktops. Thermal undershirts that are too large can be transformed into fitting sleeveless undershirts or tank tops also. Sleeveless thermals and thermal tank tops are excellent undershirts for the winter. This article will detail how to make thermal undershirts into sleeveless thermal undershirts.
There are three ways to cut the thermal top into a sleeveless undershirt. Leaving the seam on the shirt makes for armholes that are shallow, while cutting the seam off allows a more comfortable undershirt. The third way involves cutting off the collar and making a tank top undershirt.
Make a hole in the sleeve on the side of the seam where you are to cut. Insert the scissors into the hole, and cut around each side of the sleeve. Cutting one layer at a time ensures that the cuts will be even and not leave or remove excess material. You now have the sleeveless thermal top. There is no need to hem the cloth, as thermal underwear cloth will not fray or run.
To make a tank top, cut off the collar and cut the sleeves just inside the seam. Try on the thermal top, and decide if the neck needs to be wider or deeper. Decide if the shoulder seams need to be trimmed back. Thermal cloth does not roll, so you will cut about a quarter inch wider than the finished width, to allow stretching of the material. Mark the shirt and cut back the shoulders, widen the neck hole, or deepen the neck hole. Cut less and go back again if necessary rather than cut too much. Stretch the material gently when you try on the tanktop before each cut so as to avoid a good looking cut stretch and become too wide or low.
To transform a thermal that is too large, find a T-shirt that fits well and use as a guide. Spread the thermal out, spread the T-shirt on top of it, and cut back the sides about a quarter of an inch past the side of the T-shirt. Cut off the sleeves along the dimensions of the shoulder seam of the T-shirt. If the bottom is too long, cut it back. A cutoff bottom and a normal thermal shirt bottom are almost identical in appearance. Turn the shirt inside out and sew the sides together. If making a tank top, simply follow from here the above procedure for turning the sleeveless thermal top to a tank top. Cut the side and the sleeve in one piece to make ready made leg warmers; the side cloth can be used to hold the leg warmer up using a belt loop. Other sleeves can be kept and saved for leg or arm warmers and other crafts.
Cut-off sleeveless thermal undershirts and thermal tank tops are very comfortable while providing a better layer than cotton and are perfect for when layers are desired on the body but not the arms. Sleeveless thermal shirts also provide a use for thermals that are ordinarily too large to wear comfortably. And the sleeves produced are very useful in DIY crafts.
