I love to make my daughter scrub tops for her job. Her scrub tops have 3 patch pockets on them and lining them up using a flimsy tissue pattern as a guide was very time consuming and not always accurate. So I cut up an old cutting mat and used it as a template/jig for pocket placement. It is every bit as large as the pattern piece for the front of the scrub. I asked my husband to "drill" out the marks and now I can just use a fabric marker to mark the pockets on the fabric. WOW! I have literally cut out buckets of time using this method and that old mat will literally last forever!
