Using anything other than than the dirt hole, flat set, blind set, or a scent post, is just wasting time. 99% of my sets are dirt holes or flats, no sense in trying to get fancy. Dip your traps and let them air for 3-4 weeks and then practice making sets around home until you can do it well. Don't worry about a setting cloth just wear clean boots and don't kneel down. Put your sets were you find sign and regular travel occurs and you'll catch coyotes. Trapping is twice as easy as most guys make it out to be, it's putting up the hides that really isn't much fun. There are whole books out there on the subject, buy a few and come up with a method that works for you in your terrain. Good Luck
