Thanks for taking the time to reply, folks.
Sorry I should have clarified; when I said fingering I was referring to baby fingering.
As for breakage, I guess that is sort of subjective. In general, I consider it to be a yarn that breaks fairly readily when given a good pull in two hands.
In the past we've used the acrylic afghan yarn from Herschnner's (sp?), but it seems that they only put that in large skeins now, which is rather unwieldy to manage for this use. I was hoping maybe someone knew of something similar.
Most of the yarn ends up right back up on the deck but the occasionally piece does end up in the water so something biodegradable would be a huge plus.
Thank you again.
