I don't know if I was first to invent something like this, but it was my own creativity and being a new member here, I decided to share the idea.

Basically, it's a small and very effective stick-on swami gimmick that you can make very cheaply/easily. Setbacks are that you'll need to maintain it to use the same one many times (but if you try this, normally you'll have the supplies to create multiples); and it's harder to use with a greasy thumb. Just read further and share what you think.

What you need (you can google these to figure out what they are):
-Double sided foam tape: the stickier, the more dependable.
-Sawtooth hanger: consider the graphite you use and the size of your thumb.
-Pencil graphite: I just use the graphite from a regular #2 wood pencil.
-Superglue

Instruction:
Take the hanger and break it in half. If the half is just small enough to keep hidden under the pad of your thumb, you chose the right size. Cut a small piece of the tape just large enough to cover the half-hanger. Stick the tape to the PICTURE SIDE of the hanger (so that the hole where the nail would go through extends toward the tape). Take the amount of (sharpened) graphite you'd like to use, ie around a quarter of an inch?, and place the non-sharp part into the exposed hole so that the tape just holds it there. Secure it with a little bit of super glue and let dry.

That's it! Just practice with the first one and figure out what works best for you. I've used this many times and it works like a charm. Just have to remove the layer on the tape and stick it to my thumb and it's ready.

Welcome to the Café. The idea above has basically been made and done 300 different ways but don't let that discourage you from coming up with new stuff.

It's kind of hard to tell from the description but is he describing a variation of the Boon Writer???

I haven't heard of the boon writer, but I described a writer that sticks to your thumb. It doesn't discourage or surprise me that this idea has been done before. I was just in a store around the time that I heard of swami and managed to find very cheap supplies to make one out of. If I can find a way to take a picture of the ones I made, I'll post it.

That kind of describes how a Boon writer works. The Boon is about the size of a thumb tack and is reusable. I am a fan of the Swami gimmick for many, many years even having it worked on me by a gent on the streets of Bangkok in 1972. I didn't see what he was using, he hid it well. I always liked the ones that Johnson Products turned out. Easy to load and easy to ditch.

Take a pic if you can. I'd love to see it.
