I have been teaching myself designer in order to create my own template/patterns for leatherworking (wallets etc), and am wanting to create some custom brushes to mark out stitching spacing along my stitch lines. Similar to what this reddit user has done here in illustrator.
I started by taking the above users .ai file and opening it in photoshop. I am using the 4mm stitching line and thought I would try create a repeating brush by saving an 8mm section with two stitches as a png as below and importing it as a new 'textured intensity brush'.
However I am having trouble getting it to conform to its original spacing of 4mm between each stitch. Is there an easy way to make it conform to 4mm spacing each time? Any ideas on what I am doing wrong?
Thanks in advance
