Thanks Ali! I knew someone would come up with something! It's me, Jacky, by the way - Cupcake Cottons!!

Alex covers this in episode 413, I've done one recently and it's very easy

I wonder if there is anybody that can point me in the right direction for tips/instructions on how to do a scalloped border on a quilt. I have found the basics, but need help on how to calculate the size of the scallops, bearing in mind that the miniature quilt I have made is rectangular and not square! Much appreciated, thank you in advance - Jacky
