In that case, if you are going to get anything like serious then I recommend that you get a hot wire machine and the Peter Childs jobbie is as good as you can get for the price..
I gave one of our friends their Christmas pressie this afternoon. 1/2 dozen of something like these
done with my PC pen. They were quite chuffed with them and the lady has a solid tip pen and is now going to look into a wire hot jobbie. I recommended the PC set to her too.. Quite a coincidence?
