After seeing this post, http://www.xmarksthescot.com/forum/f...almoral-74554/, about knitting and felting a Balmoral, I bought the pattern and have been honing my knitting skills on some practice pieces and simpler projects. While in a local store shopping for the ingredients for the bonnet (and finding a dearth of 100% wool choices in the local stores), I came across wool yarn roving. I assume that this is yarn that has not been twisted into plies. I've looked at some manufacturers' websites, and they indicate that one major purpose is for felting. I was wondering if any of you who have knitted and fulled your own bonnets have used this, and I wonder what your experiences are. Is roving yarn appropriate and usable for bonnets?
