I've worked a lot with manos... it felts BEAUTIFULLY. Just remeber that each skein is hand dyed, so if you're going to use more than one in a project, you should alternate the skeins so it blends better. You WILL be able to tell where one skein stops and the new one begins if you only knit with one at a time, whether felting or not (yep, did that on 2 different bags). I usually knit 2 rows with one skein then switch , knit 2 rows, switch back etc. I wouldn't go more than 3 rows, then you'll have a bunch of ends to weave in... if you do 2 or 3 rows you can carry the yarn up the side.
