How to Insulate a Cup

Cup insulator

You can use a simple three-layered fabric tube wrapped securely around a cup to insulate hot or cold beverages. Not only will the beverages stay at the desired temperature longer, but your hand will also have a comfortable layer between it and a warm beverages or the condensation from a cold beverage. A cup insulator also adds style to any glass.

Things You'll Need

• 2 fabrics (jersey knit or or sturdy cotton)
• Fusible batting
• Adhesive Velcro
• Sewing machine
• Thread
• Scissors
• Pins
• Iron
• Paper
• Pencil
• Ruler

Instructions

1. 

   Create a pattern for the cup insulator. Draw an arced shape similar to the diagram onto paper. The length between points A and B is 10 inches and the length between points C and D is nine inches. The length between points A and C and B and D is five inches. Cut this pattern out of the paper.

2. Place the pattern over the two fabrics and cut them out. One fabric will be the outer fabric and one will be the lining fabric. Cut out a piece of fusible batting that is the same shape as the pattern but a half-inch smaller on every side.

3. Place the outer fabric piece with the wrong side up on a work surface and place the fusible batting piece on top with the fusing side facing up. The fabric piece will extend a half-inch around the outside of the fusible batting.

4. Fold the fabric up and around the fusible batting and iron the fabric to the batting. Be careful not to touch the iron to the batting, because the batting will melt onto your iron.

5. Lay out the lining fabric piece with the wrong side up and fold the same half-inch up around each edge. Iron this fold.

6. Place the outer fabric piece and the lining fabric piece together with the wrong sides facing each other, then pin to secure. Sew the pieces together to sandwich the batting and finish the edges.

7. Cut a 4-inch length of Velcro and separate the two sides. Place one side of the Velcro onto the outside fabric between points B and D. Place the other side of the Velcro onto the lining fabric between points B and D.

8. Wrap the cup insulator around a cup and fasten with Velcro.
