I just started doing some English paper piecing and I'm really enjoying it. Yesterday I made a couple of Inner City blocks and I'm very excited about how good they're turning out! This is a pattern that I've loved and wanted to do for a long time, but the thought of piecing them the regular way was daunting and I didn't think I would ever get around to doing it. (Picture is sideways, for some reason.

I have a couple spools of Bottom Line in silver and grey and I like it a lot for hand sewing, but I need to also get a darker color, probably charcoal or black. I stumbled upon some reviews of InvisaFil and the general consensus seems to be that it's great for EPP - strong, doesn't tangle, etc.
So I was wondering - for those of you who have used both of them, what is your preference and why? Pros...cons?
