This handy tote can be made larger to handle big projects (just add more stripe rows), or smaller, as desired. You hold 2 strands of worsted weight throughout the project and a size 11 or 13 needle can be used. Gauge is not terribly important as it is going to be felted. Be aware that felting will decrease the overall size of your project by about 1/3. If you do not use one of the suggested yarns, just be sure it is a feltable yarn! And have fun with it!
