Elle, my scallops ended up being 2.5" deep by the 5.5" wide. click on "size from quilt" and you will be ok. I made my scallops bigger than the original design. I did that in the border section to let the software draw the template for me though. You do it on Layer 1.
Meredith...thank you! I did draw a line about 1/2" above the seam line and left it blank. I didn't want to have a solid pebble thingie.....too much pebbling I was afraid (besides, it would have taken me longer to do) LOL! I like how it turned out though. Thanks!
