FROM THE USE WHAT YOU GOT FILE: Plotting tools

I've been catching up on some projects I've been wanting to do as the sailing season heads to an end. Some of which involve using my fairly new Sailrite LSZ-1 Sewing Machine. I bought a bunch of stuff on board to use and help with the planned projects. Things like tape measures, fabrics, snap hardware and the like. But, I found that I did not bring a straight edge ruler. So making straight hem lines has been a little awkward. The simple straight edge really comes in handy when extending and measuring lines too. So I looked around the boat and found my Weems & Plath Marine Navigation Plotting Tools are coming in very handy when measuring and drawing on various fabric pieces. Seems the same tools used for  drawing straight lines on a chart also help do the same on Sunbrella fabric. So I really don't need the straight edge rulers at all.
