Ohhhhh, rhombus...never thought of that! Thanks. Work is finished for the week, OH is away for the weekend so it's just me, the dog, a bottle of red and the rotary cutter!!!!! Hehehe, even have a television set up in the sewing room and a swivel chair so I can swivel from sewing machine, to cutting mat, to lowered ironing board and iron. My idea of perfect laziness and enhanced production! I just have to remember to keep the garage door shut so no-one thinks I'm at home when they call by for a visit...shhhhhhhh!
