I suppose that your choice will have to include which machine that you want to use to make the bags, if that’s what you’re going to be making at the show.
I usually take a handcrank to Quilt Shows. We always make the same quilt block in the booth using different machines. My wife calls it her Show Quilt. Usually, I’m quietly cranking out blocks while she works the booth. If I have a machine that I want to sell, I use it in hopes that I find a buyer. Other times, and especially if we got skimpy on renting space, I take Hurkie, my hurricane ravaged Featherweight hand crank. He’s also the easiest to carry from the truck to the booth, takes the least amount of booth space, and he always gets attention.
For Craft Shows, I’ve taken both hand crank and treadle machines. It depended on what I was making. I used my Singer 201K4 HC doing quilt blocks at one outdoor show, a Singer 99 making triangle pennant strings at a fair, a Singer 306W treadle making wind socks at another fair, and a Singer 185K HC doing quilt blocks at another fair.
Just operating a machine at your show will attract attention. Use the one that you like for the task that you’ll be doing.
One thing I might add, we tried having two machines running in the booth a few years ago. She was making quilt blocks on a Singer 404 electric, and I was making triangle pennant strings on a Singer 99 HC. We decided that buyers didn’t want to interrupt us to ask about our products, so they just moved on. One of us now makes sure to appear to be doing nothing except waiting on the buyers. My wife knows our products best, so I usually sew.
