Our quilt group did "all you can stuff in for $1" bags...little sandwich style zip locks (and they had to close!) These got rid of many little scraps, and were fun to watch ladies really stuffing their bags to the limit! :) Some were fabric, some were ribbons and trim pieces, etc. Christmas stockings sold well in all sizes, bibs for babies and adults, lined fleece or wool mittens in all sizes, and little clay flowerpots filled with floral print scraps sticking up cutely.

My guild shows have had good success with small quilted 'thread catchers'. We all use them at our friendship sew days to put our garbage thread bits in to be thrown out at end of day. Also small needle cases, pincushions and small zipper pouches for holding wonder clips etc. Good luck.

Friend suggested the small bags, about a foot square or rectangular sewn in long pockets, then filled with rice to heat up in microwave or freeze. Use for sore muscles etc. How about cup cozzies to keep coffee or tea or cocoa warm.

These are cute and easy.

It's also something that someone might buy so they don't have to go out and buy a whole roll of the stuff to make one.

None of you have mentioned what prices your "selling like hotcakes" items were. Maybe it depends on where you are and how many other buying opportunities visitors have available? I know I always like the $1 items, whether I buy two or a dozen! In December, I came home from one craft fair with at least 18 items at $1, from two vendors.

I just remembered an "off the wall" idea one of our guild ladies came up with. She had wooden yardsticks the kind that you find in home improvement stores (don't remember if hers had anything on them or where she got them) but anyway, she wrapped them with scraps of batting and hot glued it onto the stick. They were for running under the fridge to gather dust bunnies. I think we sold them for 2.00 and sold every last one. Stood them up in a trash can for display. This might be something the group could do and you could have a bunch to sell. assuming you could get the yardsticks at a bargain rate.

Hanging kitchen towels and sock monkeys sold well at our table.

If you're covering them over with batting, you wouldn't even need yardsticks.
Just use thin strips of wood.
Might even be able to get them as scraps where they sell lumber.

What about gadget cushions? Interfacing and directions sold here: http://www.quiltsmart.com/index.php?..._gadgetcushion I know several made them for Christmas gifts and they were well received. No affiliation.

I've made luggage tags, besides using them on luggage you can use novelty fabric and make, for example, ballerina fabric and put on a dance bag. At my granddaughter's school they all have the same bag. I got the free directions from the internet.
