Make do and mend coldframes...ideas?

Hi everyone!

I'm looking for creative ideas on how to make coldframes with the minimum of fuss. I have a selection of glass panes on my allotment but I don't want to spend loads of money on wood. I seem to remember someone on telly painting cardboard boxes with gloss paint and then putting glass over the top. Any ideas gratefully accepted!

Bright Blessings!

Got any bricks ??

Dry build, a brick box like structure - put the glass over the top.

Go to your local market and ask the meat/fish sellers if they have any polystyrene boxes.  They usually chuck them out at the end of the day and once thoroughly cleaned (the fish boxes need a good airing too) they make excellent cold-frames.

I'm using the inside of our old dishwasher covering the top sometimes with a piece of clear plastic! 

Thanks everyone! I sometimes spend more time working on recycling projects than on actually growing anything!
