I happened upon a blog one day where the person recreated Pottery Barn initial etched vases using vinyl stencils and Glass Frost spray. (if this was featured on your blog - let me know so I can link it)
So I set out to do just that for our neighbors this holiday season - only using real glass etch cream - so simple to so do - took me about 30 minutes from beginning to end...
Get one glass vase
I managed to pick this one up at a local craft store - I stopped by one day and they had a table full of glassware all for 99 cents each - I grabbed a couple larger vases - not knowing what I was going to do with them...but for 99 cents how do you pass them up.
Cut a stencil in some form of adhesive vinyl - I used Contact Brand contact paper and my wonderful Silhouette machine to cut out my stencil - but this can be easily done by free hand cutting out a letter.
Make sure your glass is nice a clean without any fingerprints , as the oils in fingerprint residue can affect the etching process.
Apply your stencil over the glass and make sure all the edges are stuck to the glass without any bubbles - once the stencil is really down clean the exposed glass again to remove any fingerprints.
Apply glass etch cream to the exposed glass - be very careful as if it gets on your skin it can burn - you are encouraged to wear gloves (but shhh I don't) - I apply the cream with a small sponge brush
Let sit for 15-20 minutes and then wash the cream off under warm running water.
Remove stencil and admire your work...
Fill with goodies (3 different kinds of cookies) and give to good neighbors...(ok the last part is all me...)
