These sheepskin soles are designed to be used with Fleece Artist Merino Slipper and the Sheep Skin Slippers pattern from Gaspereau Valley Fibres. There are holes punched along the edge of the sole which are crocheted into. After a few more rounds of crochet, the stitches are picked up with double pointed knitting needles to finish off the piece. A print copy of the pattern is included with your purchase. Please email firstname.lastname@example.org or give us a call to let us know whether you'd like the adult or infant size pattern. 1 ball of Fleece Artist Merino Slipper is needed for the infant size or 2 for the adult size (to make two adult size pairs, you only need 3 balls).
