A sign that always brings a smile to my face - and it's true
"Of course you can make it, but when?"
The one item I am currently looking for is the pot scrubbers crocheted from nylon netting.
Another item that I thought was cute was a little baggie with a cocoa mix package, a little candy cane, and a couple of marshmallows. I think there was a poem in it, also.
Location does matter. So does how the merchandise is displayed. There is that line between cluttered and sparse. If you are having a good day and things are selling, move your goods around so there aren't holes in your display.
If you get a poor location, maybe you can get your friends and relatives to shill for you. Everyone is nosy and wants to know what's going on. So if it looks like there is something fun at your table, others will want to know what it is, too.
If this is for a church bazaar, or something like that, I like to have a few inexpensive items available - even if I'm not in love with them, I'll probably buy a couple of things just to help out the cause.
And you can always make things that you know your family and friends would enjoy in case they don't sell.
