Slippy rulers
 

Do you stick anthing on the back of your rulers to stop them slipping?

I have used two things: Invisigrip-clear, like contact but a bit grippier; deck tape for skate boards! My long arm dealer told me about the deck tape. It comes in clear or black (I think). It feels like a plastic sand paper and is sticky on one side. I went to a skateboard shop and they sold me half a deck's worth for about $3! I have most of it left as I only use dime size pieces. I would use both again. I seem to remember someone putting rubber cement on the bottom...? some days I NEED it.and someday I don't!

Nexcare tape works great. You can see through it. I buy mine at Walgreens.

I've used those little round sandpaper dots that are available in the notions section of fabric stores.

I use Nexcare clear tape also. You might be able to find something similar in the UK...
it's used for bandages.

Non-skid shelving. small strip.

Te only product that I've found that really works is Grip Strips

i have them on all my rulers

I am glad to hear a good review about the Grip Strips. I have been wanting to try them so now I probably will give them a go. I have been using the Invisigrip for a number of years but it seems to be getting slippery now.

I started buying Creative Grids rulers -

I also use the grip strips and use them on all my rulers.
