That is actually a real nice first yarn!
To make it easier to spin, don't try to draft from the full roving. Split it lengthwise into thinner strips. This helps open up the fiber making it easier to draft.
Make sure you hold your hands far enough apart to allow the fibers to slip past each other when drafting.
You can also totally pre-draft your fiber before you sit at the wheel. This allows you to totally concentrate on the treadling.
Keep it up!!!
