Well the first join is done and I think this time I've really 'got it'!!!! If you look back at this post you'll see that it's a lot bulkier and sort of detracts from the flow of the design. A non tatter probably wouldn't notice but an old age tatter like me does!!!!
I will get a pdf file put up with the 'translation' of this join in my Dora Young notes when I get roundtoit!!!! I need to be sure I've got it right first so will try it on a few more motif joins.
