Below are a few examples of stained glass transom fanlights. I can make fanlights in any of the following designs or use inspiration from a different design you have seen elsewhere. You can change any of the colours, textures or inserts to match your decor. If you like you can use parts of one design and integrate into another fanlight design.
For reference the price for any stained glass work is decided by the size of the panel(s) and the amount of work that is in the design and the materials that are used (volume/colours/featured motifs). A design which is more complicated with many pieces of glass and curved shapes takes much longer to make than a simpler design and so this increases the cost.
