What does one do when you own more than 100 t shirts and most have never been worn? Recycle them. In the thrift shops they sell them for rags.
I cut them up and did some artistic dyeing. Each pant front is the back of a shirt and each pants back is the back of a shirt! Whip out that serger and in 20 minutes, the pants are done.
I also use these for mono printing transparent fabric. Two for the price of one. These green pants were the fabric which took the excess of the mono print and then I threw them in a dye bath.
My twin granddaughters are the recipient of these pants! The little tucks near the hem are for the growth extensions!
