Note: I’ve made these in two slightly different ways. Check also the second tutorial for a hot water bottle cozy.
2 coordinated fat quarters, one for the cover and 1 for the bias tape for the border.
The cover will have an opening at the back.
The cover is made of 3 pieces sewn together with a border.
Fold the fat quarter in 2 right sides together and place exactly half of the hot water bottle on top of the fold.
Draw around half the bottle leaving 1 inch all around.
Cut the fabric to obtain a symmetrical piece.
To cut the 2 pieces for the back use the front piece as a model but cut across 2/3 of the way on the long side and and add 1 1/2 inch to the small piece that goes on the bottom part.
Make a quilt sandwich with some muslin at the back and proceed to stipple quilt the 3 pieces.
When finished, cut off the batting edges.
Buy ready made bias or make your own. For double folded bias, strips should be 2 inch wide.
Sew bias to the edges of the opening at the back.
Put the 3 pieces wrong side together. The long back piece should be placed over the short piece.
Sew with a 1/4 inch seam allowance.
Once the 3 pieces are sewn together, sew the bias all around the edges.
