Not all fairy's have the same size of wings and not all fairy's are equaly tall. Because of this the wings are made in several sizes. We have standard wing sizes of 10 cm (4") , 14 cm (5.5"), 17 cm (6.7"), 20 cm (7.9"), and 24 cm (9.4"). But other sizes can also be made with a maximum size of aproximately 36 cm (14.2"). If we have to make non standard sizes a new embroidery pattern have to be made which will take some extra time. Because of this the price of non standard sizes shall be much higher. The figure underneath will explain how the measurements of the wings are taken.
To get an imprssion if how the size relate to each other I put them together on one picture.
All available sizes together.
