CrafTreat Ergo Square folder

What this tool is for
The Ergo Square uses a broad edge for smoothing a freshly laid cover. CrafTreat also describes using it to spread adhesive and move air from a flat sheet. Its shape makes it worth considering when you need to work across an area of paper or cloth.

Fit and buying advice
Check the edge you will use beside the hinge before buying. The square covers a wider contact area than a narrow burnisher. Choose the narrower tool if a spine, raised corner or board edge limits access. Compare the pencil-profile burnisher for access beside a raised joint.

Questions about this tool
Can I use this profile on a long straight crease?
For a long fold, compare the maker's straight Large folder. The square is shaped for broad contact while smoothing a surface.
Will the surface stay free of marks?
Test it on a spare piece with the same finish and adhesive. The result depends on the material, the surface underneath it and the pressure you use.
Does the tool set a hinge width?
Use a spacing guide for that measurement. After positioning the pieces, use the square to apply pressure where the cover needs smoothing.
