Hi Mary,
If I understand your question, you should be able to set the "Dimensions" to make the maze have less detail or more by decreasing or increasing the Cells Wide/Long in the Maze Creator Settings, it is one of the tabs of that dialog box (Style you see by default). There is another tab that lets you set the "PAGE" Width & Height. That one is next to the Dimensions tab in the same Settings dialog box.
Hopefully that is what you were trying to do. I would suggest if you are creating sheep, you might want to start with a mask of a sheep to speed up the process of creating the maze. What you need is a picture of a sheep and an image editing tool such as PhotoShop (Paint can do it too). Set sections in the picture to white that you want removed, set section you want set to black in the template to black. Most colors between white and black will be considered the maze template. Check out the template galary built into Maze Creator for examples. There is some information in the manual as well. If you have a sheep picture, you can email it to me and I will help you convert it to a mask for Maze Creator.
Regards,
