Hi and welcome Eire (sumting)!!
Doubleposting is not necessary, you'll get help from this board anyways but maybe it was a mistake so on to your probs.
Doing the edges is a widely discussed subject here. Use the search form wich is available att the bottom of the screen whenever you get into one of the subforums. You can choose from the dropdown list to search a specific subforum or all. Use keywords like edges, edging, slick (ing), burnish and I think you get a bunch of threads and there are some with the actual topic right in the threadname. We have just had a really strong and lively thread about this.
In short you use a little tool called edge beveler to cut the edges so they get rounded and then you use a slicker (bone, hardwood and plastic is mostly used as slicker but a piece of canvas can also be used) and whilst leather is damp you polish (some say burnish) the edges to a smooth and/or high gloss condition. There is also different aids ranging from saliva(!!!) to a sticky goo called gum-tragacanth that you can put onto the edge while slicking to make it easier.
Staining, I usually take it off before completely dry. Most times I use a sponge too apply it to get a certain streaky grain effect but a circular motion is better to work it into all cavitys and crevages. I also use techniques where I seal the leather surface with acrylic sealer/finish (Fiebings leathersheen) before staining and most often those times I let it dry completely AND for special effect I have a certain tecnique where I don't seal AND let it drie completely wich creates a very special effect.
So with both theese topics there are as many techiques as leatherworkers. Study the threads and you'll find out interesting ones that you can try.
Many of us is very inclined to help out and guide through processes individually aswell as posting tutorials. That's often how the few tuts I've done have started.
Good luck with it and give us a call for help if you're stuck!!
