Hi: Great job! Noticed your remark regarding using pencils for marking. I found pencil lead that can be used in any standard .5mm mechanical pencil called Ultimate Marking Pencil for Quilters & Crafters. This is supposed to never smear, fit stencil openings and it washes out. Unfortunately, I can't remember where I bought it and the packet doesn't give any info about the manufacturer. Can't wait to try it out
