One of my favorite ways to procrastinate is to look at knitting patterns. I can "invest" hours this way and my pattern files reflect just that.
There are some things that irritate me....here are a few.
A pattern that does not have a picture: Now...with the technology we all have this is not a hard thing to accomplish. If I like the pattern enough, I will grab the picture from the ad or listing and add the picture to my file copy. When I look at the pattern again, why I saved it will be less likely to be a mystery.
A pattern with uncorrected WRONG instructions. This one hit me again a few weeks ago when a friend needed help with a pattern she had gotten free with a yarn purchase at a store. I looked at the pattern...and looked at the picture. I thought I must be missing something. I knit it to check what I was seeing. What was I missing? Instructions that would create the cowl in the picture. My thought is that if a pattern is produced it should be tested...and proofread. Typos are annoying.... but instructions that don't instruct....BAH! I have the name of the designer tucked away in my mind and when I see one of her patterns I move on by...fast.
Bad pictures in patterns are also really annoying. Not hard to take a picture which actually shows the object. Not hard. Also....when the knit piece is not prepped well for photography....a little annoying.
Those are my big ones....
Once in a while I do write a pattern. I do a draft. I put it aside. I read it again. I take care of the pictures. I read the finished pattern again. I try to avoid doing the things that I dislike in a pattern....practice what I preach.
