Securing row cover on a raised bed

I have quite a few raised beds. I used to buy wiggle wire and channels to hold the row cover material in place, but that is expensive. I have started to use automotive trim buttons. They cost about .05 cents a piece in bulk. I drill a hole in either the wood or my pvc frame and push the christmas tree like fasteners into the hole and it secures it very well. I don't connect the body to the sides so I can roll them up and down as required. A dandelion fork pops the fastener out if I have to remove them. I have used them with greenhouse film and they work just as well on that. In my regular greenhouse i secure the shade cloth with the same type fasteners. There are so many styles of these clips I can cover a variety of jobs.

Excellent idea! Will store that one for the future....

Here you can see that I have or am still using the wiggle wire at the top.Though you can't see it there is also a layer of greenhouse film captured in the wiggle wire channel and rolled onto 1/2 pcv pipe. This is secured on the pcv with the same fastner. It rests over the back of the fence so I can use it if temps are really going to fall or in early season. I currently have the row cover secured at the bottom with the wiggle wire in the picture but I plan on using another piece of pcv so I can rapidly roll and unroll the cover as needed. A week of 80 degree weather and now the 3rd of June and it appears that snow might occur this coming Tuesday. I will use some type of bunjee system to secure and put tension on the cover. The green house film seems to stay in place even with wind and just with the weight of the pcv. Temperature swings are very wide here, so covering and uncovering is a constant issue. These raised beds just happen to be incorporated in a fence not very clear but there is a rabbit hutch, bed, tool shed, bed, rabbit hutch,bed . Rabbit manure is handy and tool shed is centrally located.
