Save some time by eliminating the "tracing" of patterns. Take your pattern, lay it over your cardstock and use your stylus to "trace" it onto your cardstock. You won't need a light box or copier for this and you can re-use your patterns again and again.

Use the Fiskars soft-tip micro-touch ones. They have an ultra fine tip that will allow you to get into small spaces and make precision cuts. You should also try to move your paper around instead of moving the scissors. This will allow you to cut a smooth and even line.

Sets that have more than one matching piece do better than a stand alone paper piecing. Even a title or matching smaller accent piece of paper helps! Other things that help are matching tags, journaling boxes, corners, borders, or stickers.

Learn how to do details. Invest in a very thin tipped black pen and a white gel pen to add detail to your pieces.

Use lots of shading on your paper piecings. Shade with chalk - use the small pompoms with hemostats to hold the pompom to do your chalking and shading in small places.

Take a look at some tole books to learn how to create proper shading on your sets. Practice shading techniques by taking a household object and shining a light on it. Note where the shadows and highlights are. Move the light and see how the shading changes.

Make your paper piecings special or unique. Try to use the latest scrapbooking trends in new and unusual ways.

Pay attention to color schemes. Invest in a color wheel and learn how to use it.

Organization

Use a set of drawers, page protectors or other filing system to keep track of all of your paper piecings. Separate them by:

1. paper piecings that have been bid on/sold but not sent out
2. paper piecings that have not been sold
3. paper piecings in progress

You can also have them packed and ready to ship as you list  You may need to combine some paper piecings for a customer that wins multiple pieces, but the packing is already done and makes shipping go faster!
