I glued it in place so I could screw it down but the glue did the job and I never got to put in the screws. What was interesting was that the double spiral produced both pieces without wasting wood
Here is the design if anyone is interested…
The wood is 1/4" Baltic Birch and it fits on one sheet. I put it up before the paint was totally dry so it looks a bit shaky but then so do I. I see I also added a cross piece to stiffen the design you can see in the photos.
Great approach with the double spiral. Many designs I see here use two cuts close together for two pieces, which leaves a sliver of scrap between them. I’m a big fan of using one cut for two pieces, like you did here.
Yes, A line does not have to close if you don’t want it to. Folk don’t realize that even a thin raster image line has a line on each side. In this case however I used Inkscape from the start to make a spiral (one line) and then duplicated it and rotate the dupe from the end point 180-degrees and made the two points one.
