I worked a two-row-repeat of pattern, to avoid a too slim triangle, increasing a whole shell every two rows, making more rows than in original pattern.
Worked the lace border elements in wider intervals, because I did not want to get a bellflower shape but a simple triangle with straight edges. Improvised a little bit to make the lace border deeper by adding some rows, according to my smaller gauge, ended with simple treble shells.
From Laceball 100 für Luise I used only the orange parts. Made a picot edging in orange around, stitching in the turning chains and row end dc/tr.
