thanks. :-)
as i starch the fabrics, i layer them in sewing order, right sides together. the number of layers depends on how many pieces i need to cut from different combinations of fabrics. i'm usually cutting through at least four layers. i limit myself to no more than 8 layers. even with a 60mm cutter, it gets too hard to cut precisely through a pile any higher than that. if i'm using shop-weight fabrics, 6 is a more sensible limit.
by layering to cut, the pieces i sew together are already matched in size and ready to run through the machine. when i'm really lucky, they "stick" together so i don't even need to line them up before they go under the foot.
