Lorna had a question about bias tape makers, and what size had I used for the napkins which I made for Rhonda's napkin swap...
I used the 1-inch Dritz bias tape maker you see above. I would have preferred a Clover brand, just because I've found them easier to use, but my local fabric store didn't have it.For the 1" bias tape maker, you cut your strips of fabric about 1 3/4" wide. What you end up with is a double fold bias tape about 1/2" wide.
There are some great pictures here on Purl Bee that show the process much better than I could explain it.
I think this size tape would also be a good size for many other types of projects like potholders and placemats as well.
Hope this helps.
