Hello everyone🌺

I need some help🙏

I’m making (trying)to make notepad.

My problem Are that we use different size here in Norway.

I have been calculatet to fit A5 notepad as we use.

But I have some problems with the spire.

You use the 5"x8".

The A5 are 5 13/16" x 8 1/4" with 100 sheet.

So the thickness/width are 5/16" or more to 3/8".

Dose anyone know the depth of 5"x8"?

I made the spine 3/4" but no place for the pen.
