I've heard glowing praise of Sharon Schambers' stabilizer from someone at a local bee, and I was thinking of buying it at Festival. After reading around a while on the web, though, I got the idea that Floriani makes the same thing for a lower price.
By that time, though, I'd started a Baltimore Album class that involves learning needleturn, so that's so much research gone by the board.
(I wonder where "by the board" came from? Hmm.)
