If you start manufacturing them now you'll have made everyone their Christmas presents by the end of August!
They are very simple to make and you don't need a sewing machine.
I made this one in about an hour from start to finish.
You will need:
- A hot water bottle (I got mine from Boots- it cost about £6)
- An old woolley jumper/ sweater/ scarf/ blanket at least twice the size of the hottie. It must be at least 80% pure wool. Wash it in a hot wash (about 60 oC with normal detergent) and or tumble dry so that it shrinks and becomes felted. You could use synthetic fleece instead.
- Tissue paper/ newspaper/ A3 peice of paper
- Ruler/ tape measure or a rough guess at 1cm
- Darning needle and similar coloured or contrasting coloured darning wool (thin wool) or ordinary thread would do.
- Sewing machine
- Ribbon (about 30cm)
Step 1: Make the pattern
Draw round it.
Move the hottie and fold it in half lengthwise.
Hold it lengthwise over the neck area of the drawing and make some marks that indicate how wide the neck will have to be to insert the bottle folded in half when its all sewn together.
Make sure your new 'neck' marks are symmetrical or you will have a lop-sided cover.
Extend the neck by the same distance again and add another 1cm for luck (I made mine a bit too short).
Add 1 cm seam allowance all round and cut out.
