Grr. The instructions for this thing are so, so very bad. I was doing fine up to this point, where another row is added to one of the motifs.
And then that same pattern is continued about 100 times until you're ready to attach to the second, smaller motif. Ok, no problem. The directions basically say to continue around the motif and don't elaborate.
What the directions don't tell you, and what you can see in the diagram if you get out your magnifying glass, is that it's not a one-to-one correspondence between the loops on the motif and where you attach. The first time around I ended up with a horribly bunched-up mess, which prompted me to take a closer look at the diagram. That look wasn't close enough though because I ended up frogging the damn thing four times in all. I have to do this three more times (I think ... the written instructions say to make two but I'm pretty sure that's wrong too) so it should be smoother sailing now that I know where the pitfalls are.
