Not too long ago, I saw an ad for knitting clamps in a magazine. I'm just finishing a sweater, and I hate using pins to keep pieces together while sewing. The advert showed these clamps were designed for holding knitted pieces together while assembling. After seeing the ad, I even visited the website, but didn't buy and forgot to bookmark, and I can't remember the name of the company. Google has been no help. Does this sound familiar to anyone? I'd appreciate any tips.
