Hi Paul
Looks like it will be a good old paper, pencil and ruler (flexi or otherwise) for a bit. Then at least I am learning the techniques. Silly thing is, I learnt it all at school, proper Technical Drawing class, not the all in one Design and Technology stuff they teach now, but that was a few decades ago. But as with all things learnt in school, if you don't use it you lose it. So quite happy to relearn it now.
So off to the local student art shop for a flexi ruler on Monday although I did find an interesting site that shows how to draw curves using different methods – **LINK**
