The Tingvoll slippers are sized by changing the weight of the yarn and size of needles used. Finer yarn and smaller needles will result in smaller slippers; heavier yarn and larger needles will result in larger slippers.
For this reason, correct gauge is crucial to knitting a well fitting pair of slippers.
Slippers require @ 30-75 gms each of two colors; exact amount will vary according to fiber content and size made. The size shown (medium, fits my size 9 foot), took about 45 gms each of the red and white yarns (Brown Sheep Company Lamb’s Pride Worsted). I have enough yarn left over in each color to make a second pair of slippers.
Generally speaking, one skein of the main color and one skein of the contrast color should be enough to make (at least) one pair of slippers.The Brown Sheep Company Lanaloft Bulky recommended for the large size would make several pairs (or leave plenty of yarn left over to make some hats or a scarf).
For the small, I used Brown Sheep Company Lanaloft Sport Weight. One skein of each color will make a pair, and for most knitters, will probably make two pairs (subtle differences in how people knit can make the difference).
Note that the needle sized used is approximately 2 sizes smaller than that usually recommended for the given yarn. So I knit my slippers on a size 6 (Lamb’s Pride usually calls for a size 8). The intention it to create a somewhat tight fabric, which will be warmer and wear better.
For the sport weight (small) I used a size 3 needle; for the bulky weight (large), I used a size 8.
Suggested yarns and needles sizes are included in the pattern.
