I recently went to my cousins wedding and decided to make them some etched wine glasses.
I made customised stencils of their first initials using contact paper which I cut out using my craft knife.
This is a really easy craft to do yourself - the hardest part is making the customised stencils! I use the etching cream and at first was a bit worried about burning my skin with the chemicals but I have never had any on my skin. You can buy it on eBay and it lasts for ages as it is reusable so you just scrape it back into the jar after the 2 minutes is up.
