I LOVE DoStix. A set of 14" long plastic rectagles in 4 sizes, place dough in between. Two each 1/8", 1/4", and 1/2" (when turned on sides becomes 1"). Just used them to get my multi-grain pita dough 1/4".
Accidentally found them on Amazon while looking for something else, but ordered from manufacturer, about $18. Go to dostixonline.com. Also usable for pottery & crafts. Happy baking!
