What do you do with good quality tinfoil trays when the food is removed? I keep them and use them to diecut and punch flowers from.
Be careful not to cut yourself as you cut the tray into sections. I cut the rim off and discard it then place the cut pieces on the cplate of my cuttlebug and cover with a b plate and run it through to straighten it all out. You will still have a few bumpy sections, but they add lots of character to the flowers you will punch out. After cutting you can do as you please, I often colour them using alcohol inks or sharpie pens.
