Love to lie down with a cup of tea in one hand and a book in the other?
Damn, I cannot keep the pages open with just one thumb...
Say no more!
The solution is a simple thumb page holder!
This is a proof of concept and will be developed to divinity.
3 layers of 3 mm acrylic.
Glued together with clear "kontaktlim".
Measure your thumb where the root of the fingernail is - that is where the holder should sit comfortably.
Changes to be made:
The width should be longer, let's say 8 cm.
