Don, I cut my tshirts apart making sure it's oversized at the design part I'll be using, then apply interfacing and cut to the desired size, then just work your magic on a design, some people like them all the same size, I work with the whole design of various sizes, I think it makes a more unique quilt! Just know that it's not really hard and I know you can do it!!! Oh yeah, check out the ones on here, there are some really cool ones!!!
