|When Candyo posted her useful review of a seam tracer a few days ago, I had one of those why-didn’t-I-think-of-that moments.
I also realized that you could use a good compass to do the same thing (plus more) in one product. You can set the distance between the two points at 5/8” or 1/4” or whatever works. Last night, while I was working on a muslin, I wanted to give myself 1” seam allowances instead of 5/8”. I set my compass to 3/8” and traced along the original cutting line to make a seam allowance of 1”.
A center wheel compass is important for keeping the separation right. My compass also allows me to replace the point with a second piece of lead, which is nice. The compass I have is similar to the one in the link.
All in all, I’ve found it easy to use and I didn’t have to go buy something new.
