Money clip rubber cement/hot glue? The current project in my sewing group is making a money clip.
My question is whether I should use rubber cement or hot glue to attach the magnets that hold the clip onto the money.
If it helps, the magnets are basically metal and the rest the clip is basically leather. The thread is waxed sewing thread and the needle is (I believe) a plastic needle as the holes are pre-punched. It’s a money clip do-it-yourself kit. If it’s hot glue then obviously I’ll be needing some help as I don’t trust myself with the hot glue applicator.
I just started the money clip:

Just finished it!:
I've glued strong magnets to various other things in an industrial context, and even fairly rigid substrates have a tendency to peal off the magnets.

Hot glue is good if it sticks well to both surfaces, and it often doesn't stick very well to things like metal.  It's easy to use too -- try it out on scrap materials and you'll be fine.

A much better option is to use a magnet with a hole in (searching on "magnet with hole" will find you many sizes), and fasten through the hole, whether by sewing or some other kind of fastener.  Alternatively sewing the magnet into a pocket can work well, but it doesn't sound like you've got much chance to modify the design.  This option does require strong magnets as you're putting material in between them.
