Seed tray help
At the end of last season Wilko were selling off half size seed tray clear propagator lids for 5p (now 75p each) a bargain so I got 20. This week I've bought the trays they fit (1.50 for 5) but they don't do a drip tray to match.
Any ideas to catch the drips gratefully received no matter how weird and wonderful, I use various disused pots and packaging for my gardening needs but am stumped with this one.
The trays are approx. 9" x 7" and will sit on my conservatory windowsill.
