Elsewhere on the Café I asked about sources for purchasing rubber wine glass covers but it seems these aren't available anywhere.

Previously in this section of the Café I had been given some great advice and help (especially from Michael Baker) for making my own rubber covers from balloons and rubber cement glue to create a rolled a neck. My efforts with this technique worked and produced a useable rubber cover. However I found that while the covers this produced worked I wasn't entirely happy with the results as the ones I had been using had a nice flat surface across the opening of the glass. By contrast the balloons, by virtue of their rounded-top shape, had some extra rubber across the opening of the glass.. This didn't stop them being serviceable and functional but nevertheless they weren't quite as good as the, now unobtainable, especially designed rubber wine glass covers I had been using.

So rather than using these balloons creations I had been repairing my old rubber covers using cut out bits of balloons and rubber cement glue. And while the end results didn't look very pretty this patching worked really well.

Having just accidentally lost nearly my entire supply of rubber covers during my last flight home from my last gig I was left with a quandary of getting spares for the few covers I now have. These were the ones that I had in my props box.

So I thought I would give making them from scratch a go!

I bought some liquid latex and brushes from a hobby craft shop and using a spotlight lightbulb as a form I set about trying to make my own. I applied about 5 or 6 layers of latex to the lightbulb letting each layer dry before applying the next. Then I used rubber cement glue on the latex on the 'neck' of the lightbulb and rolled this back to create a rolled edged opening. Applying talc, I eased the latex from the lightbulb and amazingly had a great looking rubber cover.

I tried it on the glass I use and it looked great and worked perfectly. I was though, just slightly concerned that the area just below the rolled edge looked a little thinner than the rest of the cover. So with the cover in place, on the glass, I applied some more rubber cement glue just above, and on, the rolled edge and when dry rolled it up some more. This created a much more sturdy if not quite as elegant looking cover.

I am embarrassed to say I am filled with a schoolboy kind of pride at this very minor arts and crafts achievement.

Here a link to my efforts.

The mark in the middle of the cover is the brand mark from the lightbulb!

No need for embarrassment, it is that of pride in accomplishment. Great job!

Looks good, and if it works well, that's worth your pride in achievement! Congratulations!

Very nice! I admire anyone with DIY motivation.

Nice work. I may have to have a go myself! I tried a different method a few years back but it wasn't great.

Great thinking. Thanks for sharing.

My efforts have been totally overshadowed by a ready made product that I've found which does the job way better than the latex covers I've made!

Please share the product you found!!
I just started working on these for myself after your "instructions"

Just type 'silicone food covers' or 'food huggers' into Amazon or Ebay and you'll find ones like the one in the picture I provided a link to in my opening post.

These are what I bought... only I got them cheaper than this!

Not as much fun as making my ownof course .... but they are much better than the one's I've made fro latex... Having said that, I'm absolutely positive that if I'd had initially made the right shaped form on which to apply the latex, rather than bodging the job by using a lightbulb as the form, I'm sure home-made latex covers made the way I was making them would have been better than these silicone covers for being smaller and easier to 'hide'.

Thanks......much appreciated

These silicone covers also work.

https://www.amazon.com/dp/B0CCMCMD5H They seal effectively , yet using the tabs are easily peeled off .

The two smaller sizes, 2.6" and 3.8" , work fine for wine glasses.

The larger sizes could work for larger glasses or bowls of various sizes, but I noticed that the largest size -- 8" inches -- was said to be able to fit up to an 11" inch bowl, but I could not easily get it on a 10" bowl. I was able to use it fine with a 9" inch bowl. Eventually, with my wife's help I was able to wrestle it on to the 10" bowl, so if you work with an assistant that could be ok, but I would recommend it for 9" or 8" bowl.

Let me warn you, if you want to use these for a bowl of water , the outside of the bowl and the cover need to be DRY when it is applied. So that's why you would want to use a smaller bowl -- 7.5" or 8" , maybe 9" -- because you can't be sloshing water over the side when you try to apply the cover. It's easier with two people ,even with the smaller bowl.

On further evaluation , I don't think I'd recommend these covers for a bowl production. If applied securely, then it is a bit too difficult to peel off quickly. Works fine for a wine glass, but not a bowl, although you would also want to keep a handkerchief or paper towel handy to wipe off the outside of the wine glass to make sure it is dry .
