I generally use business cards or a nice hand written tag for my labels. On the labels I include my company name, a way to get in contact with me (a URL or email address), and any care instructions, if there are any that apply. I think it is a good way to make your work feel finished, professional and it lends an air of confidence to your work. The more professionally you can present your work, the better.
Once everything is labeled I price it all individually. The only time I think it is a good idea to group price things is when you are dealing with 'stocking stuffer' gifts, or jewelry you are displaying on a board. Remember, people are paying you for something unique, so play it up. The more unique the item feels, the better.
Everything is priced, tagged, labeled and ready to go. The best advice I can give anyone about presenting work is merchandise, merchandise, merchandise. Go to a store you think is beautiful. Look at how items are presented, things are presented in a way that makes you want to touch it, try it on, and is visually interesting.
Levels and vertical presentation boards are a great way to make yourself stand out in the crowd. It is really hard to get someone to walk across a room to look at something if they aren't interested. There is nothing more boring than walking into a craft market and seeing flat tables with work lined up in neat rows. Asymmetry, odd numbers, and multiple levels are interesting.
If you need to see an example- go to an upscale, trendy store and take notes. A well merchandised store will always make more money than a cluttered and poorly lit one.
If you are selling wearables, be sure to have a mirror available for viewing. People want to see how great they are going to look in your work before they give you money. You should also be sure to bring additional lighting if the space is dark or if you have something like textiles or jewelry that is better viewed in bright light.
