My plans to cast on for the lacy dress last week were thwarted by a lack of crochet cotton stockage at every craft store in town. I even journeyed to the ever-loathed Wal-mart. Still no luck. Same goes in my quest for 40" circulars. It never fails, when I am in need of 16" circs, they are no where to be found in a sea of 29"+ circulars... So, it would make sense that when I need longer circs all I see are 16". Ugh.
DMC Senso cotton have been ordered from DiscountYarnSale.com. I still need to make a trip to the LYS to see if they carry 40" circulars- I suspect they might.
