Cardiac DNA Completed

In a previous post, I described making a small top using 3/4 inch hexagons to represent DNA. The DNA part was prepped and hand sewn together while looking after my brother during his heart surgery and short convalescence last summer. I appliqued the hand pieced part onto a background and then layered and quilted. The quilting in the background was designed using a big piece of tracing paper and transferred to the top using Transdoodle chalk paper.

Now I have finished the quilting.

I used Magnifico Thread from Superior, and experimented with using two colors to see how it would change the gray and add to the image. I was going for the impression of layers and I'm not sure that worked very well, but the quilting definitely has a lot of visual texture.

After auditioning a bunch of binding choices I ended up with the same stripe that I used for the 'nucleotides'. Note that the stripe is actually a zigzag, so to get things going around in the same direction, I had to cut strips of the 'zigs' and skip the 'zags'. Double fold binding was sewn on entirely by machine.

The method is as follows: I decide on the seam allowance using a test 'sandwich' to ensure that the fold comes the right distance to the back to cover the first stitching. Then I sew the binding to the front, mitering in the usual way. Then I stitch over the raw edge with an overcast stitch (straight stitch about 1/4 inch from edge + zigzag just over the edge). This firms up the edge and makes it really easy to pull the binding to the back and glue baste, just covering the stitching line. THEN, on the front, I use a really narrow zigzag to couch a coordinating #5 perle cotton thread down, in the ditch next to the binding. I use a regular, open toe foot -- no special foot required. This catches the binding in the back (see photo above and below to see how even this turns out) and secures everything, AND it adds a line of definition, setting off the binding.

I love how this turned out, and after admiring it a bit on my design wall, I will be sending it off to my brother for a birthday present.

I enjoyed this so much, I have a new one in the works -- more complex, with a hint of DNA replication.

Thanks for looking in,
