Here are the answers to some commonly asked mosaic questions.
Q. Can you mosaic onto wood when making an outside mosaic?
Wood isn't a good choice for an outside mosaic, this is regardless of how you seal it or what adhesive you use. Wood moves with temperature changes and is subject to swelling when it comes into contact with moisture. Sealing will not prevent it from expanding or contracting with temperature changes.
Keep wood for indoor mosaics only and look into using the following substrates for your mosaic: compressed fibre cement sheeting, marmox, wedi board or a more expensive option Ayrelite (an aluminium honeycomb with a fibreglass skin).
Ayrelite is relatively expensive and not stock by any mosaic suppliers that I know of due to this. It is a building material, one manufacturer that I'm aware of is Ayers Lightweight Panel System. Here is a photo of the some Ayrelite products to give you an idea of what it is.
Q. I am a really bad drawer, how can I come up with a design?
Tracing an image is a good way to make up for a lack of drawing skills. As you are making a mosaic you don't need detail, an outline of the shape is really all that is required. Images from children's drawing books or stained glass patterns are a great source. To learn more about tracing an image, go to our 'How to Mosaic' topic entitled: How To Create Mosaic Designs Simply - Even If You Can't Draw!
To get the image to the size that you are after you can enlarge or reduce it with a photocopier.
