First off, let me show you how I set up for a manicure. I have multiple fabric storage boxes like the one below. They have several compartments in different sizes. I use another for my stamping and acrylics and another for various other nail art like rhinestones and fimo.
You can see in the middle section on the right, I have my finger cots with the cotton balls in the next compartment behind them. Here is what they look like up close....just like little condoms.
You can purchase these in multiple sizes. People use them to protect their nails, like when you are doing dishes but they also can be used if you have dry cuticles but don't want to wear gloves on your hands. I buy them in medium and it is a great fit for me. Next step is to moisten a cotton ball in acetone and place it on your nail.
Now your ready to hold it in place by using that finger cot and rolling it onto your finger.
Here is what they look like when one hand is finished.
Now all you need to do is wait five to seven minutes and then pressing the cotton down on your fingernail, slide the finger cot right off the nail. The glitter has melted (or the Shellac or Gel) and polish and glitter slide right off with the cot. The best part about finger cots......you can hang up your clothes, iron, do the dishes, walk the dogs (if you don't mind people seeing your hands like this), you can even play on your ipad because the ipad allows you to scroll and use the touch screen even with the cots on your fingers.
If foil is still your go-to, that's cool. Just know you have another option. I usually buy my finger cots off e-bay because you can get a box of 144 for under $5.00.
Addendum: After I put up this post, my friend Veronica from Gorgeois told me she had posted on the EXACT SAME THING earlier this year. She, as usual, did a much better job displaying this method through photos and carried it through all of the removal. You can check it out here. If you are not following her already, you should.
