Similar to my last lacy vase, I’m continuing the theme of extending a pattern of lace cutouts to fill the whole surface of the vase. This piece has solid diamonds, with lines of lace between them.
The tricky part in this design was that the diamonds cross the fold lines. If I had just drawn diamonds on the flat paper and used those to place the lace, it would be obvious that sections of the lacy lines were missing inside of the pleats, and the design would have looked like a complete mess. I could have calculated exactly where the lines needed to cross, but that seemed like a lot of work. Instead, I measured on the flat paper where I wanted the corners of all the diamonds to be, then folded one pleat at a time so I could trace straight lines on the back over that pleat. That worked surprisingly well and gave a design where the folded pleats almost disappear under the lace. If you look closely, you can see some signs of the approach I used: to make it easy, I made all the diamonds the same height, so the diagonal lines are at different angles for each diamond.
