Okay, I finally made one just to try it out and see how well it worked. My son happened to be the guinea pig for this one. Anyhow, this was a very easy sewing project and you can make it as difficult and elaborate as you wish. I started out with a sewn square and a few lines. I made sure I put the marble in the maze while making this lines to make sure I had enough room. Here is one of the ones I made. It has 3 dead ends and I just made it as I went. The only thing I thik I wish I would have done differently on this particular one was make sure the backing is a solid color or make the end and beginning of the maze very clear.
This is my son working on completing the maze. Notice
how he's using two hands. He did figure out he could slide
the ball as well especially if you were going in one direction.
Anyhow, my son loved this project and took it to bed with him. Hey, it's quiet and non-destructive so I am not going to complain too loudly. Here he is using it. He found the marble and now he's just pushing it through the maze. It helps with fine motor skills and hopefully I'll add some more variety to this idea later.
