Hi Betty, Great question! There isn't a set formula, but designs created for lana generally have 1/3 the stitches that standard designs do. The thread is so thick that less stitches are required to fill an area in. If you want to use this thread on other designs, I suggest reducing density by 1/3 and testing the various parts of a design.
Here are some designs I was able to find that are made for thicker threads:

I think that's all we carry that is especially for wool. Here is another source:
