Yes, CDM that's the dog leg. When you fold the fabric into four, it is essential that you make sure the fold at the top (which has four layers) is felt with your finger tips as ONE FOLD. If you feel more that one fold, it means the fabric is not sitting exactly on it's straight of grain, and you'll get the "dog leg" thing happening. Let me know if you need more info CDM, I'm happy to take any questions. Cheerio for now, Judie B
