The first project I would like to share is one that both my children enjoyed. Miss 6 has not completed hers as yet as she has not been well and therefore her concentration has not been so good (she's a bit like here mother in that respect).
So.....project 1 was found here:

Sew Together is as sewing school in Sydney run by 2 sisters. This in itself is a brilliant idea and I'm trying to convince my close friend to start one up in the South / South Eastern suburbs of Melbourne. We'll wait and see on that one.
Anyway here is a picture of the original sunglass case as made by the ladies at Sew Together:

and here are the pictures of the sunglass cases as made by my children:

Some tips:
- use woollen felt as recommended. I think it's tougher than acrylic.
- for my 6 year old I didn't punch holes .... however this probably depends on how much experience your child has and how strong they are (pushing a needle through the felt can be a challenge)
- I did however mark dots at regular intervals to provide a guide as to where to push the needle.
- Let you child trace and cut out the shapes they would like on the case. This provides greater ownership and it really looks a bit cuter when they've cut it a bit wonky.
