some EZ Line
I have not had the best of luck with EZ Line.
As in, sometimes CA holds it fast, and other times, eats away slowly at the join, leaving a mess.
Some of that will be self-inflicted for very deliberately using the tiniest sizes for better scale effect.
Note that EZ is actually flattens, not round, so you want to us max magification with your optivisor to try and get it to lay as flat as possible.
Your Mileage May Vary.
(My go-tos remains fly-tying and suture silks [and synthetics in the latter case]--and those are often no easier to find than EZ.)
