DIY Mug Warmer Wrap with Solarize

This DIY Mug Warmer Wrap is great for keeping your hot beverages warm and not burning your hands at the same time. I don’t drink coffee, but I do love drinking hot chocolate. I use a normal mug often. The solarize interlining helps keep hot things hot and cold things cold. Make a stack of these for personalized gifts, maybe with coordinating mugs and mug rugs. I choose a kitty print fabric, because I’m a confirmed cat lady…though I only have 2 cats. I chose a print with a stripe like design, so I could center the cats. With a project this small, an all over design can get muddled. Make sure you are picking a fabric with a print small enough to fit with the scale of the mug warmer wrap. If you like quilting, you can quilt a rectangle to match the size of your mug. The quilting will be focal design instead of one print.


DIFFICULTY: Intermediate

TIME: About 2-3 hours

CARE: Hand wash and hang. Iron as needed. DO NOT MICROWAVE.


  • Cotton fabrics – Great scrap stash buster
  • Solarize Interlining
  • Smooth Interlining
  • A mug
  • Matching or coordinating thread
  • A fabric tape measure
  • A clear ruler
  • White chalk or pencil
  • Sewing machine
  • 1-2 buttons
  • Hand sewing needle
  • 1/4″ wide elastic
  • A steam iron
  • Scissors
  • Chopstick



1) Using the tape measure, find the circumference around the mug by the handle opening. Measure the height of the mug. Mine curves at the bottom, so I measured to where the curve started. Measure the height of the handle opening where it connects to the mug. Write these down.

2) I fussy cut my print, so the cats lined up well. If you have a smaller print, you don’t need to do this. If you have a distinct print and you want to center the design, I suggest drawing your rectangle around that design using the white chalk and clear ruler. The nice thing about using chalk is you can dust away the markings…great for mistakes!

My wrap part is a 12″ long x 3″ tall rectangle including seam allowance. The connector tab (goes through the handle) is 4″ long by 2″ tall. I drafted them straight onto the fabric since I’m just making one.

3) Cut out your rectangles from the outer fabric.

4) Using the chalk and ruler, trace those rectangles onto the backing fabric. Cut out the backing fabric rectangles.

5) Draft and cut 2 sets of smaller rectangles from the Smooth Interlining.

6) Draft (a pen works well) and cut one smaller rectangle from the Solarize Interlining.

7) Line up the Smooth Interlining rectangles on the back of the fabric, according to their size. You want the rough size to face the fabric, as that is the glue side.

8) Set your iron to the Cotton setting. Carefully iron on the cotton side, to adhere the Smooth Interlining to the fabric. It doesn’t take long for it to adhere.

9) Lineup the Solarize Interlining silver side up, onto the Smooth Interlining side of the large backing fabric rectangle. Baste into place by hand or machine. If doing it by machine, I recommend sewing it with the cotton side up, and the Solarize Interlining likes to bunch and slide.

10) Determine which end of your wrap the tab will go into. You’ll leave those ends open for now. Lineup the rectangles according to size, with right sides facing. Stitch 1/4 away from the edge all around, leaving the attaching end open. Leave both ends open of the smaller rectangle.

11) Cut the end corners of the rectangles at a diagonal, making sure not to cut the stitching. This will help with shaping the corners.


12) Turn the rectangles right side out. Use the chopstick to help poke the corners into shape.

13) Iron the rectangles flat, making sure the sides are crisp. Fold in the open end of the large rectangle and one end of the small rectangle about 1/4 inch and iron flat. This will help with stitching later.

14) Topstitch about 1/8-1/4 inch fromt the long sides of the small rectangle.

15) Insert the unturned end of the small rectangle into the opening of the big rectangle. Center them. Topstitch closed about 1/4 inch from the large rectangle’s end, making sure to catch all the layers at that end.

16) Topstitch around the large rectangle, about 1/8-1/4 inch from the edge.

17) Now for hand sewing! Cut a piece of elastic about 2 inches long or smaller. Insert the ends into the opening of the tab (small rectangle). Hand sew that end closed with a straight stitch.


18) This is optional. If you have a distinct print, you can hand sew around the design to quilt it. This just adds some texture and visual interest.

19) Hand sew on two buttons about 1-2″ from each other on the other end of the wrap (large rectangle). This makes the wrap adjustable for different sized mugs.


20) Put a favorite warm or cold beverage in your mug. Put your wrap around the mug, using the elastic to attach it to a button. Enjoy!
