shorten tee shirt using elastic
Shorten tee shirt using elastic is another great way to shorten the length without all the hassle of marking, cutting, overlocking and sewing.
Use a thin elastic that is the same width as the overlocking. Most tee shirts do not have a seam allowance as such, which means it have been created on an industrial overlocker with a stay stitch (four threads or more).
If I am making a garment from a stretch fabric such as tights or a tee shirt, I will thread my overlocker to a four thread machine and join in this manner.
The only reason I would use my normal sewing machine is for work such as collars or the final hemming.
Happy altering
