After I got all the shirts cut, I was ready to start interfacing the shirts. For anyone that hasn't used interfacing - it's just a thin layer that gets ironed on to keep the shirts from stretching. I used that table I made that shows all the cut sizes of the shirts and cut squares of interfacing to match.
But see that empty cardboard bolt? I ran out of interfacing before I could get all the squares cut, doh! So I've ordered more but the quilt will have to wait patiently for a week until it comes in.
I decided to go ahead and iron on the interfacing to the shirts that I can.
I only have 3 shirts left that need interfacing so as soon as that comes in I'll be ready to stitch/piece the front of the quilt!
