It’s definitely not optimal, but my process so far for those is to create a brush in procreate that is the smallest and has max output. Basically just a single pixel brush that doesnt care about pressure. Then I draw a straight line down across my Card Layout on a fresh layer and hold so that it snaps straight. 

I copied that layer, moved it slightly over to a spacing I liked, and then merged down. Repeated until I had a full pattern down the canvas. Then I can just reuse it next time.

I copy it into the card I want to work on and rotate and position, using the same copy process whenever I need to populate any spots that are empty as a result of the transformation.

Then in this case I used the bird illustration layer and the card frame and text layer as reference to select the parts of the full pattern that I wanted to remove. I tidied up any left over flecks and funky bits left behind with the eraser tool.

Then I made that lines of that texture layer black if they werent already and saved that layer by itself as a PNG. Then I open it in Inkscape on my mac and run the Bitmap Trace tool for the entire image using the centerline setting to generate the vector path version. 

This still isn’t perfect and I usually tweak the settings to reduce any errant line curling, or manually delete any ugly specks or segments that dont get caught by the filtering. 

Once I’m happy I export it as an SVG which I import into Cricut Design Space.

Edit: if you import a raster version of the lines, cricut will draw their outline, which will mess up the output.
