Sewing negative space is a technique I learned to be able to sew on fabric that isn't there. Think of it as un-appliqueing. By no means did I come up with the idea, but it sure is cool looking.
Here's what you need:
1. Wash away embroidery stabilizer
2. Glue stick
3. Embroidery hoop
4. Canvas- get a cheap one from Walmart as you will be removing the canvas from the frame
5. Twill tape- to go around outside of finished piece. You don't really need it but I find it looks neater.
6. Sewing machine embroidery foot.
7. Fabric and thread of your choice.
1. I started by cutting out the area that I wanted to sew. In this case the balloons. Use the glue stick just around the edge of the cut out area and affix a piece of the embroidery stabilizer to it. Make sure the piece is large enough to be able to be caught in the embroidery hoop along with the fabric.
2. *Make sure you feed dogs are down.* There should be a way to do this on your machine. Using your embroidery foot attachment and fabric in the hoop, sew a zigzag stitch all around the edge of the cut out area. You'll want to do this a couple of times making sure you are sewing into the fabric and not just the stabilizer.
3. Move the hoop back and forth from one edge to the other so that the criss-crossing threads are being sewn to each other. That is how you'll be able to have the thread suspended in the cutout area.
4. When you are sure that you've covered enough of the cutout area with your stitches, remove the fabric from the hoop and trim away the excess stabilizer. Gently run warm to hot water over the sewn area. The stabilizer will dissolve in the water and you are left with just the threads. Let the whole thing dry before mounting.
How I added the other elements:
I found an image I liked and printed it out on regular paper and glued it to the fabric. I simply stitched over the paper directly onto the fabric using it as a guide for the "embroidery". I then sewed the balloon strings.
The image came from a fantastic designer Jessica Swift from whom I bought the canvas image.
When you are all finished with your piece, stretch and staple it to your frame. At this point you can hot glue the twill tape around the whole thing to finish it nicely. Let me know if you have any questions!
