Love you hexagons!! I have been putting off trying them as they look difficult, however, a friend of mine did a RAK and bought me a ruler from MQCO and it's the cat's pajamas to do hexagons so soon I'll give it a try. I had both knees done years ago (not at the same time !) one is on it's 30th year and still ok. The other one was done in 1989 and it's good too. I must say though it took me a good 2 months on each one before I could walk without crutches. The physical therapy was brutal !!!
