Cut your thread length to no longer than about 18ins (45cm). This should reduce your knotsKnots can cause problems when you are stitching, suddenly appearing in your thread. In fact, they are not actually proper knots but just very tightly twisted thread. If one appears, take your needle and insert it into one of the loops of the knot and pull gently. You should find that this releases the 'knot' and you can carry on stitching.. If you still get the occasional knot in your thread, use the tip of your needle to loosen the knot slightly and then pull the thread firmly. If this doesn't work, cut off the thread below the knot and start again with a new length of thread. As you stitch, your thread will become twisted so, every now and then, let your needle hang down and the thread will naturally untwist itself.
