Looking for a slightly smaller size?
I have a similar-looking pattern in US 13 & 1 / EU 31 & 32. You can find that here: http://www.ravelry.com/patterns/library/saartje-inspired-...

Design Story
My son, who is 8, fell in love with the Saartje booties I was making for some friends, so I designed a pair of slippers in his size to look like the booties. (I also owe some designer’s debt to the Bockstar seemless variation, from which I borrowed.)

These are the next size bigger that I’ve done, for larger feet. Instead of consolidating the two patterns together, I thought it would be better to write it separately, as they are really quite different, even if the finished slippers look very similar.

Careful!
These slippers come out very slippery, so if you are afraid of in-home floor-skating, you might consider some kind of sole.

I Still Didn’t Make them in Your Size?!
You can definitely fudge the sizes larger or smaller by changing needle size or yarn weight. I did a try with doubled bulky yarn following the pattern exactly and got about a size 39 (US 8). They’re very quick to knit. Don’t be afraid to mess around with the gauge for sizes. Be sure to leave a comment about how they turn out if you do.
