I can’t find a class that meets on Saturdays or evenings when my daughter could take me because I can’t drive and have no bus service so I am having to teach myself by reading and buying books.
I ordered a book on rotary cutting by Alex Anderson, who is supposed to be one of the queens of quilting. It has these instruction for “magic numbers” that are seam allowances that vary depending on the shape of the piece you cut and it is very important whether you are on the straight of the grain and on the correct side of the 90 degree angle, etc. When I trim off the slevage (another message on that), I can’t tell where the straight of the grain is. I can guess that maybe it doesn’t stretch quite as much as the cross-grain, but it is a guess. Bias is not hard because it is a diagonal and stretches a lot.
I AM SO CONFUSED! How can you add 1-7/8 in to the grain side of a piece and then 1/2 in on another side and then nothing on the other sides? Has anyone used this book and know what I am talking about?
I thought all you had to do was add 1/4 in seam allowance around all sides of every piece so you end up with a 1/2 in seam total. Isn’t that the correct way?
Why don’t you use a rotary pinking blade like we use to use pinking shears for cutting out patterns to avoid fraying? All the clips I have watched all show using a straight line rotary blade.
