I made a T-shirt quilt for my son...and I used blocks from 4"x4" up to 16"x16".....and all in between....
(like 4x8, 8x8,12x12, and 4x8, 8x4 etc......)
it was very interesting but you would definitely have to have a smaller scale for the baby clothes....
get a math student to help calculate !!!!!!!
It was challenging but fun........but definitely will be my first and last......
good luck......
