Crowning Hat Tricks By Laurie Nienhaus    Have you been wishing for a new hat? The hat you have may hold more promise than you think! I've learned a few hat tricks from Tea Guild ladies that just might spur your own creativity.    One of the easiest ways to dramatically change a hat is to cover the crown. Tie a knot in each corner of a square scarf to "round it off." Center the scarf over your hat's crown and tuck the edges and knotted corners under. Secure with a few hidden stitches ,letting the edges drape.    If you want a little more body, do as we've suggested above with a heavier-bodied fabric before laying your scarf in place. The heavier fabric will be hidden by your scarf.    If you want a little more drama and have a wide brimmed hat, try this: Cut a rectangle of fabric the length of the crown plus one inch as measured from front to back and 2-3 times wider than the crown as measured from side to side. Pinch one short end into small pleats, pinning as you go - there's no need for exact measurements. Continue pleating until the short end measures 2-3 inches. Stitch pleats in place close to the fabric's raw edge. Repeat with the remaining short end. Center the pleated fabric over your hat's crown so the stitched ends are at the center front and center back. Tuck the edges as described for the scarf. The folds, which can be steam pressed if you desire, will fall further out from the brim, creating quite a vintage look. Cover the front with flowers and the back with a netted bow.    Lastly, you can completely cover the crown with silk, paper, or fabric flowers. Cabbage roses and daisies work best for wide brimmed hats while forget-me-nots and pansies are a better choice for smaller brimmed hats. You can take the time to stitch them, but this humble author is a great fan of the glue gun.    Now, you're ready for tea!
