I am presently sewing my wedding dress and have come up with a few tips to share.
1. Lay out slippery fabric on a mattress. Spread out one layer of fabric at a time, putting pins through each one straight into the mattress to keep it from wrinkling; then spread the pattern on top in the same way. Trace around the pattern with a pen or wheel and cut the fabric later, or just cut (carefully) along the pattern.
2. Keep track of pieces cut with check-boxes on each pattern piece. When you've cut one piece, check off one box. Then keep track of the pieces with a note pinned onto each one.
3. Mark seam allowances with masking tape on the sewing machine plate. If you have, say, a quarter-inch foot but need a five-eighths inch seam, measure five-eighths inch from the needle on the plate and mark it with a piece of masking tape.
4. Baste your hems. Instead of measuring, say, a quarter inch and ironing it over twice, baste a line half an inch from the raw edge. Press it down and tuck the raw edge into the fold. Or baste a line a quarter inch from the raw edge, press it down, and fold and press it again. Generally, baste halfway up the seam (here, a quarter inch) when the raw edge is wider than the rest of the fabric, such as at the bottom of a skirt; otherwise, baste all the way up the seam (here, half an inch).
