If you want to do multiple sizes in one grab bag, that's totally fine (just leave that in the notes), but please keep in mind that I may not have enough of one print to make matching sibling sets. (One style per grab bag, please.)
Tops & bottoms may not necessarily match to make a set, if you grab a top & bottom grab bag. I always try, but since I'm using small cuts for these, it may not be possible.
