How to Sew a Mug Cozy

Make Your Pattern

Mugs come in many sizes and shapes. This mug cozy can be custom-made to your measurements or adjusted for a "close" fit via the strap that goes through the handle. Two sizes are offered here.

• For a large mug that is 19 inches around and stands 5 inches tall, the body of the pattern piece is four inches by 18 inches. For the tab, measure 3/4 inches down on a 4-inch edge, extend a line 3 inches out from the four-inch edge. Measure down 1 1/2 inches from the 3-inch line and create a rectangle that forms the tab at the end of the pattern piece. This will wrap around the mug under the handle.
• For a medium-size mug that is 12 inches around and stands 4 inches tall, the body of the pattern piece is 11 inches by 3 inches. For the tab, measure 3/4 inches down on a 4-inch edge. Extend the line 2 inches from the 3-inch edge. Measure down 1 1/4 inches from the two-inch line and create a rectangle that forms the tab at the end of the pattern piece This will wrap around the mug under the mug handle.
• For a smaller mug that measures 10 1/4 inches around and stands 3 3/4 inches tall, make the pattern the same as the medium size, except make the body of the pattern 9 1/4 inches by three inches.

Cut the Fabric

Lay the pattern piece out using a long body side edge as a grainline. Lay the fabric over the pattern and cut it out. When cutting out the fabric, place the fabric right sides together, so you will have two pieces that line up correctly later.

Place the Hook and Loop Tape

On the backside of the fabric, along the end without the tab, sew the hook tape 1/2 inch from the edge, centered on the short edge. On the right side, front of the cozy, sew the loop tape on the tab, centering it on the length of the tab.

Pin the Fabric

Place the right sides together of the two fabric pieces, matching all of the edges. Lay the batting under the fabric and align the edges. Pin all of the layers together.

Sew the Cozy

Sew the edges together using a 1/4-inch seam allowance, leaving a 3-inch opening in the bottom of the body of the fabric toward the end with the tab, to make it easier to turn the fabric right side out.

Trim the corners, clip the corners, and grade the seam allowance. (The red lines in the photo show trimming and clipping locations.) Turn the fabric right sides out through the seam opening. Turn in the un-sewn seam allowance, pressing the seam allowance inside the cozy as if it were sewn.

Finish the Cozy

Hand-sew the opening closed. Press well so the seams are at the edges. Top-stitch the entire edge, keeping the stitching an even distance from the edges.
