I use the Karen Kay Buckley spray starch / mylar template method for small pieces, like leaves, petals, etc. It's basically the same, but you use one of the cheapie craft paint brushes to "paint" the edges with spray starch and push the edge of the fabric over the template, then you use the tip of your iron to press the fabric. Work your way around the template, paint, push, press, until the whole piece is done. Take the mylar template out, turn the piece over and press to get a really sharp edge. I prep all my small pieces in this manner, organizing with ziplock bags per each block. Stems are done with bias bars, circles and ovals are done with KKB's Perfect Circles and Perfect Ovals, and large pieces (baskets, vases, etc.) are done either backbasting or plain old needleturn.
