So here is what I have come up with. I had fun and found the possibilities rather interesting. I have only done a few examples but think I might be - finally - generating some ideas for a textile application. Not that I have a use for the textile piece, I just have some ideas about how I might produce a textile sample.
I cropped the picture (and it looks like I have flipped it too) and then traced the lines. Then I hid the original image and just copied the lines I had drawn and pasted them into a new document.
I pasted it twice, rotating and flipping the second pasting.
I pasted several copies of the image, rotating and flipping again.
Then I copied that image and reduced it, pasting it repeatedly in a block print.
Then I reduced it some more and pasted it several times more in a block print.
Once again, it looks a bit like it could be used as a print for a length of fabric, not what I was aiming for. So I think I will have a play with the second line drawing, see what I can come up with. I haven't decided on a technique yet - will play around with that some more in the next couple of days.
