I take no real credit for the main shape pattern its a very old pattern that dates back a long way. I simply edited it to fit my desired shape.

I cannot find the original myself but with to inform people of that. (It bothers me when people take vintage patterns and sell them... like you did not write it)

Numbers are all kinda subjective, but this pattern is very easy to manipulate into the size you want everything here is simply a guildline (though hopefully the sizes are useful.

2 strands is simply a recomendation for a thicker slipper that will last longer and be warmer. If you want a thinner slipper you can use just one strand I found there was not much difference in size, following same pattern + needle.

Worked flat then sewn together.

This is simply my variation of it, it has a triangle that folds up so you end up with a heel that does not have a lump like the usual version of this pattern.

Also has an icord edging to make a nice neat look for the collar.
