It can be done (but I agree, slightly expensive flats

). From each blanket, you could get a 28x28 or 30x30 flat, and have enough left over to make some cute doublers that match. 30x30 would probably give you more folding options with your babe. And they would be rather cute (if they are print ones). But if you want to try to get more flats per blanket, you'll end up with much smaller flats, so I'm not sure how you'd eventually fold them (even pad folding might not yield enough layers).
