On a lighter note on heating...................... During my first attempts at crafting, I got down on my knees near a plug (in my dining room) and used my heat gun on my work, it was only after a while, I realised I had burnt my carpet as well................. and yes, in TWO places!  Hubby was not amused, (especially as it was the carpet through the lounge and dining area) and to be honest, nor was I !!!!  I have made sure that I have bought the heat resistent mat for my melting pot............. oh well, you have to laugh ........ the marks are now disguised under a rug........ ho hum x
