a size 14 needle is pretty standard for sewing on most fabrics. not knowing what feet you have, I would suggest almost any that you can sew straigt stitches. if there is one with two prongs slightly spaced, a narrow looking foot, that is for just straight stitching. another with two prongs a little wider spaced would do the same, but allow for zig zag stitching. You don't want to use feet with brushes, or flanges on the side. Hope that makes sense.LOL
