Perfect for keeping that ruler in place. The Ruler Betty comes with ten 1/4" wide, adhesive backed strips that you cut to your own specifications. We use pieces in several places along our rulers and templates, but find it necessary to use more on longer rulers. They will keep your ruler or template from moving when cutting long strips (like 24" for example) or fussy cutting.
The Ruler Betty will glide over your fabric with great ease, but when you are ready to cut your fabric just apply slight pressure to the ruler or template and the Betty will gently grab your fabric and help keep your ruler or template from moving. Get plenty for all of your rulers!
