Irene C. Yes children's 100 % cotton fabric is used for this swap.
1. Send what you would like to receive, quality-wise. Send only 100% cotton quilting fabric. Please do not send thin or loosely woven fabrics. If it has to be starched to be acceptable, it's probably not a good fabric for this swap.
Fussy cutting means if the print is to big you need to make sure it's in the middle and not half or quarter of an object. For instant if you were cutting up an elephant you want to center it and not have a leg in one block and a trunk in another block. Etc.....
This swap is only for 5" blocks . Just buy printed children's fabric and cut it in 5" blocks.
