The Lankava Blocking Board, made from untreated birch plywood, is a handy tool for finishing knitted or crocheted squares. For example, blocking granny squares into shape is easy with the help of this board.
The set includes a 20 x 20 cm laser-cut plywood blocking board and 10 galvanized nails, approximately 5 cm long, for stretching the squares. The board features a measurement scale from 5 to 19 cm.
