This is a project cutting out letter M and using it as an effective bookmark.
We need a cardboard, I have here one inserted in my ID holder. Measured at 2x4 inches.
Start by folding it lengthwise then cut 1/3 inch as the foot of letter M stopping 1.5 inch before the top. From the middle cut straight across to meet the end of the other cut.
Then measure 1/3 inch from the other end and cut across to the side as shown.
Your cuttings should show something like this.
Unfold it to show the letter M.
This is a good bookmark for it holds the pages for it not to accidentally fall.
Other side shown.
Like something mysterious under the sheets.
