For those of you who have made this pattern, do you think I can get away with 20" circulars? My very favorite pair of Addis are in 13s, but 20" length, not the 24" it calls for. I figure I’d be okay, maybe just a little snugger around the cable, but wanted to double check with you experienced clogsters.
I realized that Bo Peep’s yarn sale being extended to the 1st was clearly a sign from above telling me to buy Cascade for my clogs immediately if not sooner. 
thanks everyone!
