I'm just learning. One of the sweet lady's at the WA/OR retreat last weekend was kind enought to show me how to do it. I spent yesterday finding a pattern and printing some foundation pieces. Today I spent sewing it. I just finished putting the block together and realized I put it together wrong so it looks a little wonky, but still not bad. I will try to do it right tomorrow.
From what I have done so far, I really do enjoy it. Once you get the concept it really is quite easy. and you get great points. Someday I will do a full project but for now, I will practice. Besides i've been wanting to make some mug rugs, this is a good way to practice and make something.
