light worsted or dk weight yarn
size 6 needles (double pointed)
one size adjustable
cast on 6 stitches and knit in garter st for 34 rows or 17 ridges
bind off but do not break yarn.
With dpns, Pick up stitches along the sides and bottom of the tab, forty stitches.
knit in garter for twelve ridges and then join on 4 dpns to knit in the round. Knit for about two inches and then begin decreases for the toe. I like to put (20) half the stitches on one needle and ten each on two more needles.
To decrease, starting on front right K1, ssk, knit to within 3 sts of end of row, k2tog, k1. Repeat on the back side of the toe stitches.
Round 2, K.
Round 3 Repeat decreasing. When 8 stitches remain, cut yarn leaving a long end to join live stitches, pull tight and bury end.
Could that be easier? Where I say about two inches, this is where the foot length can be increased. I have size 7 feet and these slippers are quite stretchy so the finished slipper looks short, but it fits just right.
The size is pretty variable, so for heavens sake, try them on! Gauge isn't as important but stretchiness of the yarn is. I am using merino superwash yarns, here, and they have lots of bounce. The whole slipper takes but 2 hours, so if they are too big, or too small, it becomes evident early on and its is simple to make adjustments. Be brave and knit on!
