Making clips non slip???

I am contemplating buying the Gripzies but am just not sure....
I have only done a couple of clips with the shelf liner and don't like the look of it.
Also when making the clips non stick is best to stick it to the top or the bottom of the clip????
If you stick it to the top of the clip how well do they stick when you have done a middle piece on your clip and glued it to the underside of the top.
Hope my queries make sense ?? !!! ??

Hi, I sell 2 types of non-slip linersin my shop. Both are self adhesive. Personally, I like the non-slip grips over the gripzies, but that is my personal preference.
