OK, I'm going to show my um, backwardness.. or something like that ..lol..
I press my fabric, mark whatever is to be cut, add seams, and take my nice sharp shears for strips and one of the many small pairs of scissors to cut the pieces if it's something small or intricate.. told ya I do it all "by hand". I tried rotary cutters when they first came out and just didn't care for them. Although I do have one and a mat..umm....I know it's somewhere around here.
