Blotz - Mitten Blocker PairA mitten blocker stretcher, just right for hand knitted mittens. This is made from 4mm birch ply, so strong and durable. The design has a four sheep cut out of it which will allow any dampness to dissipate. The thumb is supplied as a separate piece which can be tied on to the blocker on a loose string to keep them together. It has a jigsaw style fixing to help hold it in position within the mitten. This is for a single blocker only.
