Traditional European embroidery techniques such as "azure embroidery", which draws a pattern like a light path while pulling the woven thread with embroidery thread, and "blackwork", which neatly embroiders geometric patterns with black thread, are applied to make palm-sized brooches. The small surface area makes it easy to try, and the joy of going out wearing a beautiful piece is a source of creativity. The brooch base comes in two types: round and oval. Made of heavy sepia-colored metal, it is perfect for adult outfits.
