Reading?

I've been reminded several times lately, how important the ability to read is whether it's reading: music, literature, news or written instruction. The ladies in my crochet class had to tell me more than once that they passionately wanted me to present some information about interpreting written crochet instructions and diagrams. I take it so for granted but having just met their requests, I'm now more aware of my own  ability to read and work out a pattern. I'm also grateful to the designer of this beautiful square for her ability to write out the recipe and publish it so that I could make it. I'd like to incorporate it in a shawl.
