Blocking Questions...
So, here it is: the Anne Orr 'Large Table Doily'. I'm working on the last full round and have gotten 1/2 way around. (still having trouble with the last split ring in each of the diamonds...they're getting better...just not as nice as I'd like)

I will probably soak and block the doily after this round and before the 15 small motifs are started. I have so many questions that I'm not sure where to begin.
To block:
1. Should I start in the center then alternate between the center and outer rounds?
2. What do I do with the unfinished thread space?
3. Do I direct all the unfinished thread space to march in file or can it find it's own way?
So, you get the picture. I need some suggestions as to how you might progress with a mess like this. I've got the pins. I've got the blocking foam. Now, two more days of tatting and then...it's off to blocking land.
Please, help bring the blocking anxiety into a manageable place.
Happy day!
John
