yes rulers and templates are expensive because they have to be 1/4" thick, don't make the mistake I did, I thought I found a really good deal, they were like 1/2 the prices I'd seen elsewhere! so I bought several sets for $75, when I got them I realized that they were DESIGNING templates, only 1/8" thick! A must have is a stitch in the ditch, I've heard a lot about the linetamer (haven't bought it yet tho) and there is a 4 in 1 tool that I see used a lot, I do have that one
