Tip for keeping ruler from slipping
When you do not have the sandpaper like spots to put on rulers to keep them from slipping while rotary cutting....use double stick tape and a small piece of shelf lacy looking cushion type liner in three places. Works great.
Checked name on a roll of this type shelf liner and it said, "Easy Liner", did not really tell me much as to what to call it to post here.
It is amazing what we can find to serve our purpose when we do not have the real thing.
