Stumbling around I came across a twist on the traditional compass rose design made using a Celtic knot. This one from Da Vinci's Workshop was made for tile but can easily be adapted to stained glass or mosaics. The design is copyrighted so please ask their permission or use policies if you use it.
Just finished an oval version of my popular Holy Spirit window. Added in this design was two banner areas marking an anniversary. The window size is 18" x 24".
Final destination is a church in the West Indies on the island country of Nevis.
