Trim tray... Homemade alternatives?

Hi all,

I am a few weeks away from harvesting and I have some nice trichome covered leaves. I see that trim trays are a thing and look like a great way to catch all them trich's when harvesting...

Does anybody have any experience with homemade alternatives? They're quite expensive where I am but figured there must be another cheaper alternative.

Thanks in advance!

I went to goodwill and bought a rounded 4x4 glass table and chairs for $10. Kept it for over 20 years as my curing and trim table. Bring your razor blades

Ah wicked! That's given me hope. And inspiration!

Thanks
