I do a lot of embroidery testing and I would recommend that you use a heavier, cut away stabilizer for the rest of the blocks as well as follow the other suggestions given here about hooping. I recently attended a class by Mr. Floriani of Floriani Products and his answer to this problem also was to use a heavier (ie more stable) stabilizer and it has been working for me. In fact, I found that the heavy stabilizers that I own that I didn't use much are now getting more use than the others.
