You try it in a different yarn than the pattern calls for? I sometimes do that but am not very skilled at converting patterns to a different gauge. I may get to your skill level someday...but I doubt it.
I found the Tahki Kimono Jacket from their recent booklet and thought it would look perfect done with this tweedy Beatrice yarn I got from Ranee, but the pattern turned out to use a very thick chunky yarn. I quailed at the thought of converting the pattern to such a different gauge, and started knitting it with two strands of the Beatrice. So far it works, but keeping fingers crossed.
