Photo left - looks like there's no room for a foot! With wear, the knitted-in thrums will felt down and be like an insole.
BUMPERSNeedles - 4.5mm or size that will give you a firm, but not too tight tension.
Yarn - A handspun yarn or any purchased yarn that will knit up well with size 4.5 needles. The yarn I used is handspun wool (when I wash it, I know it will felt so I knit with a looser tension). If you knit up slipper with a non-shrinking fiber, have your tension firm, but not too tight.
Thrums - This pattern says to cut sliver or roving into 5" sections. I used wool straight from the sheep (washed, but not carded). The staples were naturally 4.5 - 5" so I pulled off enough to make it approx. 2 or 3 times the thickness of the knitting yarn used.
- Cast on 39 sts. (to obtain smaller or larger sizes, decrease or increase number of stitches by 4's).
- Knit one row
- Purl one row
- Row 1 - *Knit 3, next stitch knit with the wool thrum* continue to end of row.
- Row 2 - Purl row
- Row 3- Knit row
- Row 4 - Purl row
(REVISED with this 3 row DECREASE)
Row 1 - Knit 2 together across, knit last stitch
Row 2 - Purl
Row 3 - Knit 2 together across
Break yarn leaving enough to gather toestitches and sew up. Draw up remaining stitches with darning needle and sew shy of half way towards the heel. Then sew up back seam. An edging of crocheting can be added to the top if desired. (see the red pair below. I also added 3 thrums into the center seam to fill in the space on top of the foot).
