Once the trics start plumping up, you may be able to see them with the naked eye, if not, loops can be found cheap at camera stores, or even a magnifying glass from some place like walmarts. The next time I go to Harbor Freight, I'm getting a hand held microscope, but hell, I'm almost 60 & I can't see shit! LOL!
----OK, figure about 8wks to finish from the time you put them in 12/12. That's only an average. It varies.
