Installing a Professor Patch on a Patagonia Sweater

Lay your sweater flat on a work surface, damage side up.

Measure the length of the hole.

Measure the width of the hole.

On a piece of paper, mark the endpoints of a line that measures the length of the hole, plus one inch.

Mark the center of the two endpoints.

From the center, turn the measuring tape 90 degrees. Mark the endpoints of a line that measures the width of the hole, plus one inch.

Sketch a curve connecting the endpoints of the length and width.

Draw a straight line connecting the endpoints of the width, going though the center point.

Fold the paper in half on the straight line.

Cut along the curved line. The piece you have just cut out will be your pattern.

Lay your pattern over the hole to verify that it is the correct size and shape.

Lay your pattern over the piece of fabric you’ve choosen to use as a patch.

Pin your pattern piece onto your patch fabric.

Using fabric scissors, cut around the pattern piece.

Inspect the patch, going back to clean up any rough edges with scissors.

Lay the patch over the hole, positioning it where you would like it to be.

Pin the patch into place.

Insert a ballpoint needle into your sewing machine.

Slide the sleeve over the arm of your sewing machine, just like you’d put the sleeve over your own arm.

Align the very edge of the patch with the needle.

Sew around the edge of the patch, turning the sleeve as you go.

Sew until you come all the way around, retracing your first stitches.

Slide the sleeve off the arm of your sewing machine.

Clip any loose threads.

Repeat on the other sleeve if you want symmetrical professor patches.
