Tops Rovings

Does anyone in UK know where to buy wool rovings or cotton tops for Needle Felting/embellishing crafts ?
Feltmakers, spinners and weavers may have the answer to my question. The problem is I don’t know anyone in these fields. I am knowledgable about many aspects of textiles but this is a new area for me.Can anyone help? I would be happy to hear from people who are involved in this craft I live in the U.K.
Hi. These places seem to be willing to ship to the UK.
http://www.halcyonyarns.com They sell fiber individually and in handy little packs of different colors.
http://www.paradisefibers.net Which is a very nice site, my brother ordered my first fiber from there. (I’m a very new spinner + a knitter)
They both seem to have some very interesting fibers, wool tops and cottons. Although the ones at paradise seems to come in more interesting colors and you’re able to buy by the ounce. I don’t know, that part of the halcyon site confused me.
Oh, you probably know, but considering the way you worded the question, you do know that cotton fiber doesn’t felt, right?
