Question: Are these wine glass lampshade made of glass?
Document: These solved two problems at once. I would recommend however that if you were to use this you have a large wine glass anyting smaller than a 16oz long stem wine glass will not look right. We used Libbey 16oz pinot grigio glasses and they looked amazing with purple and blue lights in them.
I'm using these for my wedding with some battery operated tea lights. I tested them out on some wine glasses at home. They are thin, transparent lampshades made of paper, it seems. It's a little challenging to put them together as you have to be careful not to tear them, but the final product is so pretty!
Only problem was I thought they were glass but they will work just fine. I guess we mis-understood description. But loved them anyway
When i saw this product, I fell in love with if for my wedding... It's was littel different from other table number.One reason why I only gave  4 stars is that paper is very thin.....I know it has to be little thin for the light to go threw but I wish it was made so it does not rip too easy
Wedding is 8 months away...and I tested one shade w/the short ridged wine glasses... OMG!!!!! I LOVE it!!! so pretty and simple. Thanks
These shades are very nice & they were a hit at our daughter's wedding. They appeared a bit thin when we received them, but one we connected them & set them over the wine glasses, they were beautiful. We used battery powered tea lights which worked perfectly because they were on the whole time & since the shades completely cover the glasses, no one knew they weren't real. This was a good purchase!
Perfect for my needs! And will be using over and over again. Never have to worry about creating table nos. when we do our parties at our Community Center.
Love these! Using them for my wedding and enjoy them so much more than regular numbered tables. Especially if you want a romantic feel.
I ordered another brand of these that are plain and the material is slightly thicker, and they are much easier to put together and they stay together better than these. These are pretty and they will do the job.
I like the idea but not the look now that there home the came very fast and were wraped nice but im just not a fan of how plain they are ill have to dress them up befor the big day.
Answer: No. They are plastic/paper like and fit over the wine glass/or any glass. If you put a tea candle in the glass - looks pretty into the evening
