I use it for the body of the tote as well since I like mine to stand up. I use it in runners sometimes as I really hate when they don't lay flat . I use it in all kinds of stuff. When using it in the base of the tote if the tote is already constructed I double fold it , for a stiff base , and cover it and stitch thru the layers. Do use a larger needle ! I find that in many non-bed quilts I like more structure than a typical batting. I really like it for wall hangings . It can get pricey so wait for interfacings to go on sale or use a coupon. Sometimes Jo'anns will have a 50 percent off all interfacings and then have a coupon for an additional percentage off total .. thats when I pounce.... like a hungry cat looking at a big fat .....
