Here is a sampler afghan a going away present f0r a fellow fiber artist made up of 20 different sampler 12 x 12 inch squares each from a different knitter and/or crocheter and afghan squares all crocheted together and all finished with a crocheted border.
Afghan measures roughly 4.5 ft x 5.5 ft
My own square is the pink one on the very bottom edge 3rd from the left side and is of Ella Rae worsted weight yarn made in Romania. Knitted in diagonal garter stitch which guarantees a perfect square with very little casting on and no binding off at all.
