I'm still plodding on with the oval doilies and I think it was a good decision to work all three at once even though I do sometimes get into a bit of a panic with which set of destructions I should be working on!!!
Now this round worked in the tan colour is the slightly more complicated one. The chains are spiral chains. They're easy to do once you get 'in the zone' but there is a catch in that the middle doily the stitch count is slightly different. That's when I did get BC3 freaking out.
Once I'd done a couple of chains it all fell into place.
