I have found it impossible to find slippers that I like. All of them are either too much or not enough. If they cover your entire foot they have enough insulation to keep your feet toasty warm on a 10 mile hike in the snow. Seriously. I wish they made snow boots as well insulated as a typical winter house slipper. The solution, of course, is to make my own. I am so happy that I know how to sew.
The pattern is Green Pepper 837GP. Green Pepper has some very interesting patterns for things you might not think of making yourself. I have made the slippers before and I wasn't entirely happy with the result but now I'm experimenting.
The ones I made before were all polar fleece but earlier this year I found this great soling material. Since I used that I had to make insoles of polar fleece. I wish I had taken pictures of the process. What I did was, after sewing the slipper together with the soling linked above, with the slipper still inside out, I sewed the fleece insole over the top of the slipper, with the right side of the insole down and leaving the heel open. Then I turned it to the bottom of the slipper and hand sewed the heel. I hope that makes sense. I fear that I'm not very good at explaining things.
As you can see, they don't match. These are actually my second attempt. The first ones were perfectly matched with an orange dot on top of each one but they turned out a little too small. The ones I had made before were a bit too large so I tried making these just a teensy bit smaller but they ended up too tight. So I tried again with the fleece I had left and ended up with the ones you see in the picture. I am mostly happy with them. The heel seam bothers me a bit, which is embarrassing to admit since it's hand sewn. I might try to re-work it, but it's really not too bad.
I made a pair for my husband with a full lining. They're brown so they wouldn't show up well in a picture and, anyway, he's not around to model them right now. I'm thinking about making a pair with a full lining for myself.
The pattern includes all whole shoe sizes from infants size 0 to men's size 13. I can sew a simple pair in less than half an hour. With the insole or lining it takes a little longer, naturally.
