Ok so we each need to make a different block. I say anywhere from 12x12 to 12x 18 it's for a female so let's find out seeing the consensus is family first so Linda and abonda what is her favorite colors.
We can't all do zippers so maybe buttons someone said they used a garter the old ones they attached each end then they could fasten and unfasten then maybe a snap flap.
Again the most important thing is be sure they are well attached so they can't be removed and put in their mouth.
