Building Blocks 3 - finished

Here are the filled in blocks. I decided to switch the positions of the orange and purple ones from the mock-up which I think looks better and am rather pleased with it. The shading works reasonable well, especially from a distance:

Yellow wasn't too bad in the end though it is still noticeably lighter than the others. I tried to get around the difficulty by using slightly heavier patterns in that block than the others. On the close up bellow you can see that the darkest area is a tapestry stitch to get nearly complete coverage and the other two are ones I used in a previous experiment, from the post titled 'Experiment 2, which came out at the darker end of their respective levels.

The other two blocks that were particularly interesting were purple and orange:

The lightest area of orange shows the importance of direction. The pattern I was copying from had the waves positioned vertically, and initially I did the same but it it looked ridiculous so I tried horizontal and it is now one of my favourite light patterns. I should have taken a picture of the bad version but I had unpicked it before the thought occurred to me.

The dark purple section shows that too complex and small a pattern doesn't read properly. The dark orange shading above is very fiddly but it works because there is enough variation that you can immediately see how the pattern repeats. The purple one looks like a knit or darn, the pattern is virtually impossible to see. I suppose it might be useful at some point if I want to sew a figure waring a jumper but otherwise I think I'll chalk it up to the learning curve and forget about it.
