I would agree with Maria Galea. Start with the SignPuddle you have begun and create exercises that match the handshapes and movements you have already recorded. This way the material is familiar, and as you work together you can create a textbook that works for you. I started a handwriting book for Ethiopian Sign Language which I can send you as a way to get started, if that would help.

Hello everyone in the group!!!

I am Dali from Tunisia, I have been studing from you all every day with the help of all the raised questions, and specially from the nice books' offers sent to me by dear Valerie and SW team!!!
The Good News are; I am going to teach SignWriting in a Very famous Tunisian University "Ibn Charaf"!!!!
This dream has come true, all of the Tunisian Sign Language interpreters are going to learn SignWriting!!!! that's amazing!!!!
For this reason, as I lack experience in teaching SW, I wish that you could help me with your nice advice, specially from those who had had such teaching experiences!!!
I know that you will do help me out of love for deaf and for SignWriting which has become our mission to spread it in our countries and develop its use!!!
I do thank you a lot, and I will appreciate every single help!!!!
Blessings to everyone of you!!!!
