Anyone who wants to see a Wedding Ring Shawl in progress, go check out missalicefaye. She has completed the center for her shawl and it is magnificent! I just finished the second pattern repeat thanks to her kick-starting my ambition. Only three and a half more to go for the center :-) A round of applause for missalicefaye and her beautiful, inspirational work!
On another note. misalicefaye mentioned that information on making a shawl frame could be found in one of Hazel Carters books. She is absolutely correct! I have that book. It's in "Shetland Lace Knitting From Charts" by Hazel Carter. It's available at a fair price at Schoolhouse Press. Basically, she tells you to take 4 lengths of thin wood, she suggests 4 feet, nail or glue the corners to make a square. Then, using a length of strong thread (one for each side) she tells you to thread it through a point of the edge, pass the thread over the frame and catch the next point. No pegs, no holes, just over and around to the next point. On line I've also seen people using PVC pipe and joins. This way you could possibly break it down easily but you'd have to be sure that it didn't rack. With PVC, you might also make other shapes so circular shawls could be blocked.
So not only is missalicefaye a wonderful knitter, she is also a font of information:-)
