Hamburgers for a sewing snack? Why not? This set of 4 extra heavy (3oz/85g) cheeseburger pattern weights are fabulous for heavier weight, shifty fabrics and also for larger pattern pieces, though they work perfectly well for other fabrics as well.
Each burger is approximately 1.5" (4cm) tall and 2" (5cm) wide, though variations are expected just as when you grill your own burgers. Each cheeseburger weighs in at approximately 3oz (85g).
Though these look good enough to eat, please don't! You'd likely break a tooth. Though they are non-toxic and quite sturdy, edible they are not.
