Hi, I am making this baby quilt and I used the inexpensive high loft polyester batting from Walmart. I stitched in the ditch around each block and around the borders. I have seven inch blocks and I am a little concerned that the batting in the blocks might bunch after washings. I don't have any experience in quilting yet just using my walking foot so I can't really quilt the white space. Do you think it will bunch? What can I do if it will be a problem? The only other thing I can think of is to put my quilting guide on the walking foot and do another row insided the blocks to make the unquilted space smaller, what do you think? Not sure how this would look. Any advice is gladly welcomed.
