Don't worry about cutting up those favorite and precious T-Shirts that are still in good shape (or not).
They are going to last a lot longer in this quilt than shoved in a drawer that no one will ever see.
This quilt is to be enjoyed from all sides and directions so the placement of the squares needs to be a random layout. Don't lay them so they all face one direction, TRUST me on this one!
On some T-shirts the 10" square template won't always get all of the logo or printed piece that you are cutting out, but no worries. The person the quilt is for will know exactly where that T-shirt came from. I try to focus on the most important part of the screened print, e.g. Date, country, state, town, year.
