You know those neat, crisp corners on quilts and professionally sewn napkins that you look at and say “I could never do that?” You’re not alone; we’ve been there! We’re pleased to report that mastering mitered corners is easier than you may think, especially when you’ve got the right fabric. Our brand new Lightweight Cotton Twill (perfect for reusable napkins and table linens) has just enough structure to make crisp corners, but is light enough to be easy breezy to work with. It prints vibrantly and is brilliantly wash fast, so your new napkins will hold up. Follow along as we reveal the secret to sewing crisp, perfect mitered corners.

Prewash, dry, and iron the fabric before starting. Your bobbin thread is what will be showing, so be sure to pick one that coordinates with your fabric. We used one 29″ x 18″ fat quarter of Onion Rings by Zoe Ingram.
Step 1: cutting your fabric
Begin by cutting the white selvedge edges off your fat quarter. If you’re starting from a yard, cut a 29″ x 18″ rectangle of printed fabric.
Step 2: fold and press edges
Once your fabric is cut down and before you begin to sew, you will fold and iron your edges. Begin by folding over an edge about half an inch and iron down the entire edge of one side. Be sure to press firmly with the iron, as this will create a guideline for your mitered corner without having to draw a line with your pen. For our napkin, we will fold over the fabric edge by half an inch and iron the entire edge and then fold a second time (half an inch) and iron again. This will create a clean edge on the wrong side of your napkin. Repeat this step for all four sides.
The fold lines should be visible when opening up your fabric, and you will notice that a square has been created, with the outer seam bordering it on two sides. The corner of the square closest to the center of your tea towel / napkin will actually become the outer corner of your finished napkin.
Step 4: mark and trim your corners
Step 5: fold and pin
Fold your fabric in on itself at the corner you just snipped, right sides facing. Pin or clip the fabric together to hold it steady.
Step 6: sew your corners
Sew your mitered corner stitch into each corner. Starting at either edge, sew from the diagonal fold toward the edge of your fabric, and half inch from the fabric toward the fold. We highlighted our fold line and stitch lines with the erasable marker.
Step 7: snip
Snip the “bulk” out of your corner.
Step 8: turn the corner out
Using a chop stick or blunt end of a stick, turn the mitered corner out.
Step 9: fold and press
Fold in the raw edge and press with your iron
Step 10: edge stitch
Edge stitch your hem! Be sure you use both top and bottom threads that coordinate with your fabric. Use a cotton thread if possible.
You’re done! Marvel at how neat and professional looking your napkin is!
