great to know your starting work on adapting a bag full of magic, it will be interesting to see the transformation. i haven't had any other offers so as long as you wish to continue then the project is still yours; providing you think the material is good enough to move forward to the next stage, which will be performing it.
Are you still interested in adapting a bag full of magic for theatre ? have you read the blogs. You would make a great Dewi (That's a complement or a challenge depends on how you take it) his character was based on a guy I knew, when I worked at a hostel for the homeless. (Lots of stories to tell from there). drop me a line and let me know.
