I first bought the little clear dots and also the sandpaper dots. They works well but what I did not like about them - with the clear dots - the rulers edge was not completely flat on the fabric while the sandpaper dots were always "blocking" something that I was trying to see.

Which leads me to my most recent find... Rubber Cement (OK before you international folks ask - I am told by others that in some places it is not easily available outside the US). I went to a Machine Quilters Expo in Providence RI and had taken a class on longarming with Dustin Farrell and he suggested using it. I tried it and love it. When it gets nasty with thread it rubs off nicely and gets a new coat. You can see through it, the ruler lays flat and grips perfectly. I apply it and let it sit until it drys before using the ruler. AND did I include cheap?? LOL

I use it on every single one of my rulers and love it! For me, it makes a huge difference in how well I cut.

My experience with Invisigrip duplicates PaperPrincess's experience. I now only use Invisigrip on smaller rulers and use sand paper dots for everything else. I've even put sandpaper dots on top of Invisigrip if the rules was still slipping, and that worked.

I like, but I do not love it because sometimes my rulers still slip. I used to use stick-on rubber circles on the corners, but they are fairly thick and I was cutting at an angle sometimes - under the ruler and getting an inaccurate cut. With anything that raises the ruler up off the cutting surface, it is essential that the blade be completely straight. Having failed that requirement more than a few times, I pulled all the rubbers off my rulers (leaving behind sticky glue to clean off) and now have Invisigrip on them, with the exception of some specialized templates from Shar (Quilting From the Heartland); she includes little felt circles and I use those because they are thin. She also has no lines on those templates so there is not the issue of covering up markings.

I spray the back of my rulers with basting spray, then lightly rub the excess off. It grips the fabric fairly well. The first few times you use it, it grips too well, but after that it grips just right.

And, of course, if you don't like it, you can wash it off.

Yes, I like the dots too, I have them on some of my rulers. I they clear so you can still see through. I tried this sheet that you peel & apply on your rulers (are they invigrip?, don't know what's called); mine peel at the corner.

I love it and highly recommend it. In addition it keeps the back of your ruler new and easy to read I have a problem of wearing off the numbering or the yellow lines can't tell you how many rulers I have done that to they tend to last with invisigrip and then they don't slid!

What also works well and I got the tip from a LA teacher is use the skateboard mini-logo gripper tape. On their website, it's $5 for 9 x 33 piece and you don't need that much. It does scratch acrylic, but holds to the fabric with no damage.

I have the TrueGrips on my rulers and they work great. Also found that you can use the centers of the circles for the smaller rulers and can cut up anything left-over into pieces that are useable. That way, you don't waste any of the silicone fabric. They are easily moved, but don't obstruct any lines on the rules or patterns on the fabric the way sandpaper dots do. Haven't tried dabs of hot glue, but will next time I run out of TrueGrips pieces. :thumbup:

I have it on my rulers and love it .
