so i bought a set of french curves for patternmaking a while back, right

they're nice, they come in a handy package i can store them in

but they're hard to get back in, because it's a flat plastic folder and the pockets are precisely measured

so i just had the bright idea of using some stiff plastic file folder tabs to make a raised edge i can slip them under

even managed to get the in the right position to keep the hook curves from snagging the lip of the plastic.
