To block or not to block? Knitters and crocheters are often have strong opinions on the subject, but if you decide to block your granny squares, then this Scheepjes Blocking Board is ideal. The advantage of wet blocking means that your granny squares will dry to a regular size with straight edges, which makes assembling your project easier and gives a more professional appearance to the end result. The board (available to purchase separately) comes with 8 plastic coated steel pins which can be used as required to make squares, rectangles, triangles and octagons. This pack contains 4 pins which would be a welcome addition to the pack and enable you to block more complex shapes.
