We're here for you!
I know it's IMPOSSIBLE to read through 69 pages of posts for this knitalong! I've requested from "management" to create a way that we can roll knitalongs into their own "forum"...where we can post specific "topics" such as THE BACK, THE FRONTS, THE SLEEVES, etc. This would make knitalongs so much more organized and user-friendly!
Anyway, it may come along someday, after other KnittingHelp upgrades are accomplished!
You shouldn't have any problem with the pattern. It was really easy, and there were no Major pattern errors that I can remember. Maybe one small glitch, but it was minor, and might be corrected in the newer versions of the pattern now! Check online. If there is an error in the pattern, they will declare it and give the correction.
Acrylic makes a fine sweater! It will keep you warm and cozy, and a great benefit is WASHABLE! Yay!
