Holder for Whiteflies Trap (Sticky Yellow Paper)

To keep whiteflies population under control around my tomato plants (they started with my chilli plant, now they are trying to expand to my tomato plants), I purchased some sticky yellow papers, but since my tomato plants aren't fully grown yet, I had problem finding a solution how to hang those papers.

So, I designed this, added slight curve to hold the paper straight.

I used barbeque wood sticks with ~2.7 mm diameter.
