I have made a felted box with lambs pride bulky. For that pattern the yarn was doubled. I have a front loader so I ran it through twice, and then visited my neibhbors machine. It did felt but retained some stitch definition, but I think because it's garter stitch. It's very sturdy, there is a pic on my Ravelry page. I'm newamy there too. I have felted lambs pride worsted wt with beautiful results.
