Whilst I was demonstrating heat embossing at a demo session in the store I work in I was talking to a lady & explaining how the thermo graphic embossing powder worked & showed her whilst talking. She eagerly gathered powders, pads & a couple of stamps and came back to watch the rest of the demo. At that point I had got out the heat gun & started heating. The lady was watching intently & asked if a hair dryer would do the same job as she had already overspent with all the bits items she was holding, I explained it didn't get hot enough & would also blow the powder away. I told her that people had used a toaster and added to use a wooden peg to hold the stamped image and gently hold it over the toaster whilst it was on until the powder changed.
A couple of weeks later she came back again whilst I was doing a demo to buy a heat tool as the toaster method didn't work as it caught fire & set off the smoke alarm. I said i was sorry to hear that to which she added she had also burnt her finger trying to retrieve the stamped image from the toast slot !!!! It turned out she had posted her image like a slice of bread & turned her toaster on & left it.
