Step 1: Materials
Pencil, pen (small diameter works best given the dimensions of standard erasers)
3M Foam-backed Removable Adhesive Mounting Squares
Optional: Lightweight ruler or letter opener
Step 2: Cut Grooves in the Eraser
Cut grooves in the eraser with the Xacto knife – they will hold the pencil and pen. You can also cut an optional slice to hold a small lightweight ruler or letter opener.
Step 3: Apply the Removable Adhesive Mounting Squares
Remove one side of the liner tape of the 3M foam-backed Removable Adhesive Mounting Squares and apply it to the back (i.e., smooth, uncut side) of the eraser. Make sure to cover the entire back of the eraser and then trim the adhesive squares as necessary Use a fingernail, Xacto knife etc. to press/score the adhesive squares firmly against the eraser – since this is a removable adhesive, we want to make sure that it is securely adhered to the eraser.
