try doing meandering on small quilt sandwiches made from your scraps, once you get your rhythm and your stitches look pretty good I would then try different loops and motifs. Also recomend, if you don't already have them is Machingers to grip the fabric sandwich and a product called Supreme Slider to make the bed of your sewing machine slippery. One more thing check out Patsy Thompson's website, her videos are wonderful.
