Fabric cutting with contact paper

Worked 23 cm Obitsu pattern, loaded to Silhouette software, edge traced, made 3 mm outline, cut edge.
Cutting mat + black swimwear fabric (double stretch, polyester) + ConTact clear matte on top.
Cut 12 by 12 piece from fabric using cutting mat and rotary cutter and slightly bigger piece of contact paper.
Burnish really well.
Settings - blade 4, thickness 33, speed 4 double cut. Blade 3  single cut didn't work at all.
Saved the Contact pieces to use as pattern template, they are still slightly sticky.
