We recently had a customer that wanted a LOT of t-shirts included in their quilt. I had to limit it to 42 t-shirts. That is a LOT of t-shirts and results in HUGE quilt.. The most we can load on our quilting machine is 6 blocks wide. That is 6 blocks wide (14" blocks, plus sashing, plus borders).
We have always limited our quilt sizes to 36 blocks. Keep in mind that is a huge King-sized quilt. However, this customer insisted we use 42 t-shirts. Of course they were Harley Davidson t-shirts. OK, I have to admit we have a soft spot for H-D t-shirts. Hubby had a '74 Sportster before he met me. He named her 'Dora'. So, how could we say no to this one?
