When a pattern is well written you don't notice, just proceed with the knitting but when it's badly writtern, what torture.
I always look for schematics and flow. I like to check measurements to make sure I'm on target for the size I want. Do I have to flip pages back and forth to get to charts and pattern stitches? Will it be easier to copy the pattern and have loose sheets to re-arrange? Should I cut and paste the stitch definitions closer to the chart?
What an interesting field to work in! I wish you good luck with joining it to knit and crochet.
