By utilising the same wire frame that I had put on the seedling table a month back I already had most of what I need. All that remained for me to build was a clear plastic cover. Though not as easy as I first thought. It took me sometime to come up with a way of fastening it in place. The difficulty being I had two conflicting requirements:
1. Hold firmly in place even under extreme wind conditions.
2. Be a quick and effortless task to remove for the gardeners.
I had successfully met these requirements with the netting cover, but by the mere nature of netting it is far less affected by the wind than a sheet of plastic. I was rescued from my dilemma by Melanie with the idea of elasticizing the corners just like a fitted bed sheet.
To fasten the elastic to the corners of the sheet I decided to use eyelets (little mental donuts). The particular eyelets I used however didn’t seem to be designed for thin plastic sheet. They have a slightly sharp edge on the inside that when installed using a hammer, as instructed, they partially cut through plastic. Unfortunately I didn’t notice this until I was on the last one. So if you try this at home I recommend using a couple of washers on either side of the plastic.
Once I had my eyelets in place I then went hunting around the house for some elastic. Alas I could not find any suitable so I changed approach and used a rubber band and paper clip. Oh the things you can do with a paper clip. However I didn’t go with putting one on each corner, instead I just used one of each end, pulling the ends tights.
The back of it I fastened even tighter with a couple of string tying it to the legs of the table.
When complete I felt very chuffed with my creation, it looked good and seemed to function well. Sticking my head in there with the plants it seemed very warm and cosy. The next test was to see if it could handle the wind and by day 3 it was starting to look like it was going to be a raving success.
But then on the morning of day 4 I discovered it like this. Oh well, looks like it is back to the drawing board.
