... a set for double wedding ring quilts with blocks/melons measuring about 10" ...

Check you pattern catalog before getting the set; the block is pattern number 1398 TUCKED HEARTS and has been in the store for quite some time. Make sure you haven't already purchased it. 1991 DWR MELON TUCKED HEARTS is a brand new addition.

And, of course, purchasing as a set is the best buy for your money (discounted at nearly 40% from single purchase prices.)
