I thought I was pretty slick folding the page to 8th’s then marking with a template and cutting out with scissors leaving the folded solid edge till last  
Works for 30 cal.
Prolly not flash enough with only a tin lid template.
Ha
Keep them in an old tobacco tin as well
Never could quite get 1 moa.
Consistent enough after a while
Maybe a envelope would work better
Least my bore is real polished now and easy to clean.

I made my patch cutter from a piece of brass about 1/16 (.062”) thick stock I cut about 6 at a time using a sharp blade in a box cutter. The paper stock is 8.5 x 11. After pulling 6 sheets from the ‘book’ I stapled the end with three staples to keep the paper from getting separated then cut the patches on a hobby cutting mat. One trick is after you make the pattern roughen up one side with 36 grit sandpaper, this prevents the pattern from sliding about when you hold it down with your finger. I shoot a lot and also in competition and this method is fast and the patches are as accurate as your pattern is.

I bought Paul Matthews book.  Your instructions are easier to follow thanks to photos.  Well done!
