My sew group has a craft table several times a year. We make enough to pay for our retreat costs for the group. Presentation is the key. Nothing piled on top of each other on the table. Every item is showcased. We do not use dark fabrics like civil war. Bright happy fabrics sell. Different size snap bags sell a lot. They are priced to sell as our other items are more pricey. One thing, the thread has to match the fabric, no white thread. White top stitching looks cheap. Fabric rope bowls, hot pads and coasters sell fast and then again stitching thread to blend in. We sold all the very large hot pads we had at our last show. They were about 3ft round. I made a big 3ft round bowl and it sold as soon as we put it on the table to another vendor. You don't need dozens of different things. Choose a few, make them quality, and change up at every sale.
