The colours are nice - two shades of yellow, rust and brown. The yellows and rust are crepe, so ideal for crochet as it gives a nice definition. Together the colours look good.
I enjoyed doing the Erika Knight's hexagons, and I wanted something similar. In Jan Eaton's book 200 crochet blocks I found a pattern for a square block in trebles without the gaps that you get in granny squares. It is a very easy pattern, easy to do and easy to follow. I memorized it after the second row.
So now I have finished the yellow blocks. The rust yarn turned out to be thinner than the yellow, so I can't put them in the same blanket. I tried the brown one. It is thicker, so no good either. The brown yarn is an ordinary 4 ply, ie not crepe, but it must be spun with a z twist because it splits very easily, so it is more awkward to crochet. The yellow yarns were a dream.
That means that I'm heading for two baby blankets - one yellow and one brown - instead of one adult sized. I'll leave the rust yarn for crocheting together. I still enjoy it very much, and I wonder what I can find to do on the bus next.
