This project was a long time coming to fruition what with getting enough tees from the recipient and at times when I could dedicate physical and temporal space to it. It feels GREAT to have it done.
I don’t have the piecework skills nor the inclination to get too fussy with the cutting, so I kind of needed tee shirts whose fronts could be cut into 15" squares. There were a few that were too narrow at the armscye to work - especially as I had the owner remove the backs and sleeves prior to sending them to me. Those I put together in a little “collage” on the back. As with all the tees, these were stabilized with fusible interfacing - but then framed with bias tape.
The back is flannel cut extra large so I could just fold it over to make the binding. You can see the quilting there: it has diagonals across the squares and stitched-in-and-around-and-adjacent-the-ditch. Neither my machine nor myself are suited to quilting, but she knew that going in!
I don’t have measurements, but it’s just a little shorter and a little more narrower than the packaged twin-sized cotton batting.
