I made one for my DSIL using her racing tshirts. I had never made one before, but got some help from here. I knew I needed tricot interfacing and not Heat-N-Bond, but that was about it. I knew I didn't want to make just squares, I wanted something different. I chose a snowball with alternating nine-patch pattern. Not only was it alot of fun, but it was a great, positive learning experience.
