Slowly sewing

Or at least cutting. I got the velveteen cut out yesterday (aside from the collar and tabs). Hoping to the get thing assembled today and then spend some time over the weekend whipstitching seam allowances. As for the cloud, it's just under 6" now. Looks like 2 repeats = 1 inch. I am a bit worried that I didn't buy enough yarn though. A question for those who are real knitters, will I get any sort of extra length after blocking? (It's knitted with a lacy pattern, every 6th row is a YO, K2tog, and it's 100% Shetland wool.)
