Hi Morri2. Have you discovered the magic of how to join in new fleece onto the leader? The little hooks of the fibres catch onto the twisting leader and hold the join all by themselves. Once you have that bit under your belt, it doesn't matter how often your yarn breaks because it's so easy to rejoin.
I think it's well worthwhile to practice wheel control before you try to spin at the same time. I grew up with a treadle sewing machine so have never had a problem with using the wheel that way, but if you are finding you have to turn it by hand, you cannot also spin at the same time, because you need two hands for that. Practice stopping and starting the wheel and treadling slowly. It takes a while to learn to stop it just past top-dead-centre, but it needs to be there to be able to set off again hands-free in the right direction. Another point is that if your wheel is not properly oiled then turning the wheel will always be difficult. I oil mine every couple of days to make sure it runs freely.
With fingerspinning, don't worry if you can't do the folding in half bit (I hook the middle around one of the maiden uprights, a door handle, anything, then bring the two ends together that way). The important bit is to learn about the fleece you are working with by drawing it by hand, seeing how far apart your hands need to be, how thick or thin the particular fleece wants to be spun, and things like that.
Don't try too hard with spinning - relax and enjoy it - let the fleece and the wheel do the work. Your hands are just there to guide the fleece to where it wants to go. Too tense and it doesn't run freely. I find if I'm tired or tense then I can't spin at all and would just rip it all back the next day anyway
