I have read about blocking in my books - and I have the side edges tucking under - this makes my measurements inaccurate and it looks louzy - has anyone had this happen to them and how did you solve the problem. Thanks

By "tucking" under do you mean that your side edges for your stockinette stitch swatches are rolling in?

What kind of yarn did you use? And what kind of blocking technique did you employ?

If you used yarn that was acrylic, or had a high percentage of acrylic, it is almost impossible to remove the roll unless you "kill" the yarn with lots of heat. This makes the yarn become limp -- which isn't always a bad thing -- but is frowned upon for these courses. However, the Committee understands this issue with acrylic and I believe they will tolerate a little curling or rolling in.
