Creating roving vs. batts

The past few weeks I've been trying to concentrate on getting products together for the up coming CT sheep and wool festival. I have a bunch of handpainted pin drafted rovings done so I thought that I better make up some batts as well to have some variety. For some reason the batts have been harder for me artistically than any of the rovings that I do. I played around yesterday down at the mill for a while and it seems that the big carders are a little trickier because they card the fiber TOO well:). The colors that you want to keep a little seperate tend to get a little more blended than they would if they were on a drum carder. I tried doing layers, but I didn't like the fact that you couldn't see all the colors that you were getting and photographing a batt like this would be really hard to say the least. The next thing a tried was kind of mixing up the colors and the fibers. I got a much better result this way because you could see all of the colors that you were getting, but there is still some work that must be done.
My next plan is have things a little more planned out than I usually like to do. I am going to take a couple of colorways that I usually do as handpainted dye them up in indiviual sections and then try and make a few batts this way. Normally when I make batts I do it because I'm have lots of random colors laying around and don't have a real particular order that things go onto the carder. I've never really pre-weighted the fiber before making batts, but in the long run this will hopefully make things a lot easier because there won't be anymore guessing. It may also bring some new creative thoughts to the whole process and who knows, maybe some new colorways will be born.
