Sometimes you just have to spend some time making whatever the heck you feel like... even if it's completely useless to you in the moment. It's what studio artists call experimentation.
The textile samples above are inspired by the book Stitch Magic by Alison Reid.
Below is a robe covered in sashiko stitching from the collection at the Museum of International Folk Art in Santa Fe. I've always loved the look of sashiko, which is a Japanese form of quilting using running stitches to cover a piece in patterns, but never tried it. Yesterday I gave a little go of it to mend some holes in few pairs of jeans. I loved the results.
