Clippy mat or proddy mat?..we call them proddy mats others will call them clippy mats. They are really hard wearing, I have some down on my kitchen floor that have been there 15 years!This one is nearly finished (it's been on the go for 2 years!) It's done on a frame which was made from an old bedstead by my husband's Grandfather. They were made slighly differently by my side of the family, we didn't use a frame , it was just held and worked on your knee, usually with an old sharpened peg! I've inherited a lot of 'prodders' but my favourite to use is made from animal horn, it's the one third from the left.
