Do a search for earlier posts on this subject....it has benn talked about in recent months. Basically, you can attach them to jigs or hang them under a float solo, or drift them w/ a corky. Use a needle to thread them on the leader.
I use these things called "Zipper worms". They're about 2" long and segmented, actually they look very little like a worm, but they work great. Get a package of those and #4 red Gami hooks and your in business. Count five segments down the worm and insert the hook, run it through the worm down about 5 or 6 more segments and push it through. Drift fish it just like you would corky and yarn. I started fishing the pink worm with this technique at the end of winter steelhead this year on the Alsea and Siletz and it proved to be very effective. On those rivers not many people were using them, so I think the change created a lot of strikes for me. Good luck and let us know how it goes, the Sandy and the Clack are my "home" rivers and I'm looking forward to trying the pink worm on them this summer.
