I made several T-shirt quilts when I was just getting into quilting and before I truly knew what I was doing, didn't use a pattern, but hey, it worked! The designs on the shirts were all different sizes, (the first 2 I did for my twin sons--by age 9 they each had over 30 extra t-shirts
that still fit!
) I measured each design and determined a few widths that would work together and put them together in columns. I used the lightweight interfacing, cut to the appropriate size then ironed it on
before cutting. I also used 1/2 inch seams. Because I was making them for kids (and I didn't know how to do anything different
) I simply backed them in polar fleece, turned them like a pillowcase, and tied them. The boys are 15 now and still love them.... very soft! The only downside to t-shirt quilts? When they're tossed on the bed, it looks like a pile of laundry! HA!
