There is a little color pooling but I was more concerned about knitting it correctly so it doesn't bother me too much.
The Ribbed Cardigan is blocking and I have started the zipper hunt. Ann suggested Zipperstop.com. I think I will order from them. My opening is 21" long and zipper comes in 20". I think half an inch on either end will be fine. I cannot wait to actually wear it. I love the fit.
