I started chopping it up into 4 in squares. I felt a quick pang of "Oh dear...this is a perfectly lovely shirt that I'm destroying" But I reminded myself that it was free fabric and plowed ahead. I was left with a pile of scraps, a pile of squares and two ties that I saved for some unknown purpose. (why must maternity shirts have tiebacks?)
I overlapped the squares, then sewed down the middle to make a very long, skinny, ruffle-y scarf. I doubled up around my neck and got my 4 year old assistant to take a picture.
