Welcome to the fount of all analogue knowledge George, this site is a sanity-saver when you get to the head-banging-against-the-wall stage - so just ask and all will be revealed - just made the most originally stupid mistake in the darkroom ? no, no - no original mistakes here, some have made the same mistake 40 years ago and some of us made the very same mistake yesterday, so you're in very good company. If you were excited about 35mm just wait till you start printing those medium format negs - that'll get the pulse racing.
