If I read your post right, it sounds like you attempted doing a quilt after one practice sandwich. It takes a bit more practice than a single go. Moving a whole quilt is much different than moving a practice square, so you need to get your stitching down before you can move to the next step.
Gloves REALLY help a lot. You can get 'real' quilting gloves from a LQS or try garden gloves with rubber nubs from the dollar store. Really aid in controlling movement.
