Alright, the pictures suck cause of the reflection, and I have no in-progress pictures, but i'll explain as well as I can.
These are roughly the adhesive 'dots' I used, which were originally for scrapbooking purposes.
Romeo's lid, the smallest;
Because I wanted to make sure the foil would stay, I wrapped it around the lip of the lid, using two sheets overlapping to cover the space desired.
Here is where I wrapped the foil around the lip, creasing the foil as necessary and trimming also.
On the corners I put the adhesive dot directly on the foil, then pressed against the metal of the lid so that no adhesive is exposed.
Valentine's lid;
Valentine's lid is a custom wood and mesh frame, so rather than wrapping under the lip (since there is none), I creased the foil to the inside raised edge of the lid and wrapped around to the other side to apply the adhesive dots.
And finally, Shanti's lid;
Repeat of Romeo's lid, as it's the same style. I accidentally used too much foil, so ripping around where foil wasn't supposed to be made an easy fix.
hope this explained a little ^.^'
