Security envelope plaid 0 ▲ skeetmotis 1 hour ago · Tech · hide · 0 comments 10 by 10 minus 1 and 10To make this plaid pattern, start with a grid pattern rotated by 45 degrees. Set up a 10 line by 10 line grid and on each side of that grid, remove one line.Note that the blank areas in the pattern were caused by printer problems. No comments yet.
