• 9” X 12” Craft Cuts of Kunin Premium Felt in:
o Candy Pink

o Olive
• 9” x 12” Craft Cut of Kunin Classic Felt in:
o Baby Pink
o White
• Basic sewing supplies
• Embroidery floss
• Cotton Batting
• Ribbon


1. Fold the blue felt in half. Lay your hot water bottle on it, with the bottom of the bottle on the fold, and trace around the bottle, leaving at least a 1” margin around it. When you come to the top of the bottle trace as shown in the photo. The cover goes onto the empty bottle via the top, so you will need adequate space to fit it through the opening, as shown in the photo.

2. Mark two points where the neck of the bottle curves in.

3. Cut out water bottle. Cut slits on the marks at the neck of the bottle shape. Make sure the slits go through both layers of the felt and match-up.

4. Create a design. I used simple shapes to create a folk-art flower. Get creative! Flowers, hearts, animals, the possibilities are endless! Once I made my design, I cut the pieces out different colored felts.

5. Lay the design pieces onto one side of the hot water bottle shape, pin in place, and stitch onto the top layer. Do not stitch through both layers. I handstitched mine on, but you can also attach them with a sewing machine or even using a strong craft glue.

6. Once your design is attached, cut a rectangle of batting, slightly smaller than the hot water bottle shape, and pin in the middle of the felt piece. Make sure your design is on the other side! Stitch in place.

7. Once the batting is in place, fold the felt piece, right sides (the side with the design) facing. Stitch around the bottle shape, leaving the top, neck portion open.

8. Turn out the bottle cover right side out.

9. Insert your hot water bottle into the cover. I gently folded mine in half and slipped it through the opening.

10. Thread the ribbon through the slits you cut at the neck, bringing each ribbon end up from the back. Tie at the bottle’s neck.

When you aren’t using the hot water bottle, you can use the ribbon to tie the hot water bottle’s lid onto the cozy.
