How do I set the line width when using DrawLine? Can I use a button / buttons to change the line size and colour?
A very good way to learn App Inventor is to read the free Inventor’s Manual here in the AI2 free online eBook http://www.appinventor.org/book2 … the links are at the bottom of the Web page. The book ‘teaches’ users how to program with AI2 blocks.
There is a free programming course here http://www.appinventor.org/content/CourseInABox/Intro and the aia files for the projects in the book are here: http://www.appinventor.org/bookFiles
How to do a lot of basic things with App Inventor are described here: http://www.appinventor.org/content/howDoYou/eventHandling .
Also do the tutorials http://appinventor.mit.edu/explore/ai2/tutorials.html to learn the basics of App Inventor, then try something and follow the Top 5 Tips: How to learn App Inventor

Use these blocks to set the properties of width and colour
Use logic, lists to change these with buttons
Thanks for the links. I have actually done most of the tutorials and I’m gradually finding my way round but its a slow process. Lots of things I still don’t understand. I won’t ask a question on the forum until I have tried to work it out or look up the solution on the tutorials / documentation. I’ll keep trying. Thanks again.

Excellent. Thank you very much.
I usually use a Spinner with preset values from 1 to 50.
1, 5, 10, 15, 20, 30, 40, 50
For color, I like Italo's color picker.
It's a bit advanced but really nice:
