As I'm using a charm pack instead of a layer cake, I've cut the leaves only for one dresden first, to check how it will go.
As you can see:
I have 24 leaves and not 21 in my circle.The leaves are half the size of the original template, but I used standard 1/4" seam allowance, so after sewing all 21 leaves together I discovered that I couldn't form a circle without adding 3 more.
Mmm, at least I hope it was not the result of my stiches being so inacurate.
I'm quite pleased with the result (I wasn't going to use the black but I think it makes the circle more interesting).
Now I need help with changing the size of the remaining templates :)
Alternatively I think I could try to sew everything at 1/8" seam allowance... (with my not so very acurate stiches... ouch...)
What do you think?
