One of my sons ( age 49) has been making a quilt out of pieces that I had already cut. (They are 2.5 x 5 and 3 x 5 rectangles that are/were salvage pieces from fussy cutting I Spy squares)
He has no cash invested in it, but he sure has a lot of time invested in it already. He's definitely learning to appreciate some of the effort involved! He's even developed a close personal relationship with a seam ripper. And fallen in love with a Singer 404.
