And while we are on the subject of t-shirt, turn your t-shirt collection into a quilt! Above is a dance t-shirt quilt that I did for one of my daughters. I took her dance t-shirts, and basically cut the fronts/backs into same sized quilt blocks.
But before I cut the t-shirts into quilt blocks, I backed the shirts with fuseable interfacing, to have a bit more strength to them. Then used a plastic square for my guide, used my olfa cutter and mat and clear ruler, plastic square and cut out the blocks.
I used the techniques listed in Nancy Johnson-Srebro's book Rotary Magic book, for cutting out the strips that I put in between my quilt blocks.
I also used her techniques in binding the quilt (and my Mom's techniques too).
p.s. The other quilt pictured here, was one I made for Stanley School in Victoria, Texas. Took old t-shirts for the quilt, donated by teachers and students. It was a remembrance quilt, in that the students were moving to Chandler elementary school. This was part of a fund raiser for the PTA/School. Made pillows also, with the t-shirt fronts that didn't fit into the quilt.
