If you want some of my starter I can send you some. It will take a few weeks for me to prepare it. I dry it out and send it in an envelope in the mail.

Neat way to batch it out!  You might be able to adapt my dropper loop jig to suit this and make it a little easier.  I'm thinking a piece of foam around a dowel where you put the spool so it has some friction as you pull, maybe a crank on the output spool to take up the slack as you make each loop.
