I needed to insert some press studs today for the first time and just thought I would look for some instructions first. These are the neat and tidy looking ones you bang in with a hammer, not the sew in type.
I found a great (and amusing) tutorial on CraftStylish by PepperberryAndCo. Very easy to understand, unlike the odd diections on the pack.
I only made 3 changes/diversions from the tute. I interfaced (fusible) behind the stud site; hammered on my desk over a towel (naughty) and used a mini dumbell to bash it instead of a hammer. What? It was handy!
