I used to do the same with stencils and then I got one that was too long for the file and it sort of fizzled out. Also I have sets that are in a single packet bu, like you, I really liked being able to just flip thorugh the file rather than digging through them. Alo, I find that they get tangled and easily damaged when just in a pile. Maybe I'll find myself revisiting the file method if I have a stencil sort of day during The 100 Day Project. 😁

Always more things to try . . . more fun to be had.
