So after the chicken wing experience (thanks to Geraldine) I thought I'd play with the hearts in a similar fashion.
Now this is a matter of 'guess work' as to whether things will lie flat when they're finished. I'm good at guessing!!! Least on some things. This is perfect. No 'tweaking' needed. I will get the pattern sorted and put on the web site - sometime.
So, I present the joined outside in hearts doily!!!
