The Strip tube Junior Ruler from Cozy Quilt designs
The smaller version of the Strip tube ruler. This makes quick work of cutting accurate triangles from jelly roll strips. Stitch strips into a tube then using this ruler cut triangles to the size you choose. The ruler also saves waste of fabric. Larger strips can also be used to create larger blocks
The ruler includes detailed instructions - no maths needed for cutting 1" to 6" triangles
I have used these pliers for turning large cotter pins 1-1/2" & 1-3/4".
They are heavy and large to use with small cotter pins although it is possible to use them for the smaller joints it is more difficult to get a tight turn. I would recommend the smaller pliers for the smaller joints.
