Owlvamp -- Take a break and just take care of yourself. No swap until you are 100% back from surgery. I have plenty of squares to make a couple quilts.
Two months will give us time to find the correct fabric used in I-Spy quilts and fussy cut as necessary.
To answer your question I would say let's swap as before: 20 swatches per bag/6 bags max, and add a twist, but this time with true batiks. (Just my thought.)
Take care and heal fast.
