I’ve never seen an extruder here in any of the three Michael’s in my area, nor the two Hobby Lobby stores or Joann’s. They do have them in the clay crafting area, but they are tiny, (approx. 4 inches long and 1/2 inch? in diameter) it would be easier to roll each than to use that tiny thing. LOL I know you can find them online, but I just never think to go searching for them…maybe I’ll do that right now. :)
BTW: The clay crafting supply aisles have great items for fondant work, teenie tiny metal cutters, tools, molds, etc.
