On Youtube Lindsay Weirich/TheFrugalCrafter she has video on setting up a crafts table lots of tips. There is also by a lady who makes ornate decorative crafts with laces/trims a good vendor table setup video it has many views.
Small item to sell and easy to make: cocktail size fabric napkin, maybe a small embroidery in a corner.
Sell single, set of 2, set of 4, set of 6. Add some hard candy to some and color foil.
Junk journals are quite popular you might make some of those.See Lindsey Zenor for tutorial on easy simple JJ.
Seasonal ones Fall/Autumn, Christmas are very popular and sell well. So far I have not seen a Hanukkah journal yet but those would also sell.Supplies to make JJ also sell well think little bundles fabric/laces/trims/buttons. Search Etsy to get ideas. Pinterest is also great for inspiration. Fabric/lace ornaments. Those shopping list notebooks you can embellish the covers with some pretty scrapbooking papers add trim and add a novelty pen. Makeup bags.
