I used up nearly all of the 150 yards of Jess's HDT "Chilled Mess" in size 60 that I had purchased! I thought I had loads but surprisingly no, so I'm glad I got the bigger skein. There are just under 48 inches of lace. A hanky doesn't look that big but you still need quite a bit of lace to go all the way around.
I hope I'll find the time to attach the lace to the hanky very soon so I can finally show you the completed project.
