How to Decorate a Graduation Cap With a Chanhua Silk Flower

How do you decorate a graduation cap with silk flowers?

A chanhua graduation cap is a 26 × 26 cm mortarboard covered with hand-wound silk flowers instead of paint, stickers or glitter. Every bloom is wrapped individually around a copper wire frame, so the surface is three-dimensional and stays that way. It takes 16 to 20 hours, which is why it should be started three to four weeks before graduation day.

If you have never tried the craft, what chanhua is explains why the flowers are built on wire rather than stitched — that is what makes them hold their shape on a flat board.

Why decorate a cap with silk flowers instead of paint?

Most decorated caps are painted, and they photograph well for exactly one day. Silk flowers behave differently:

The trade is time for permanence. A painted cap is a costume for one afternoon; a flowered one is the thing you keep on a shelf afterwards, which is usually why people choose it for a graduation in the first place.

What is in the kit?

You supply two things yourself: scissors and a lighter. The lighter seals each thread end — pass it briefly through the flame so the silk cannot unravel months later.

How long does each stage take?

That adds up to 16–20 hours of work spread over three or four weeks. The reason to start early is not the hours — it is the curing time. Glue that has not fully set will let a bloom slide out of position, and on a flat board a single crooked flower is visible from across a room.

How do you attach the flowers so they survive the day?

1. Plan the layout on paper first. Trace the board, then place the templates on your tracings until the arrangement looks right. Moving flowers on the real board risks smearing glue.
2. Build the blooms completely before attaching anything. Wound, shaped and glued centres first; the board is the last surface they touch.
3. Use the adhesive backing sheets, not extra glue. More glue means longer curing and more chance of a slide.
4. Work from the centre outward. That way the outermost flowers sit over the inner ones, which is how the arrangement stays flat.
5. Let it cure a full day before you pick it up. Then handle it by the edges only.

Who is this actually for?

Three kinds of people end up making one:

• Graduating students who want a cap nobody else in the hall is wearing, and who would rather keep it than throw it.
• Parents, partners and friends buying a graduation gift. A handmade cap is a gift of hours rather than money, which is the point.
• Craft lovers who want a real project. The build is repetitive in a satisfying way — the same motion, many times, with a finished object at the end.

If the recipient would rather wear something afterwards, a silk flower brooch is the same craft on a smaller scale, and a hydrangea hairpin is a shorter first project if you want to learn the wrapping motion before committing 20 hours to a board.

How big is the finished cap?

The board is a standard 26 × 26 cm mortarboard, so it fits the same head as any graduation cap you have worn. The finished surface adds roughly a centimetre of height where the blooms sit, which is worth knowing if the cap has to fit under a hood or a hat during the ceremony.

What do you do with it afterwards?

Keep it out of direct sunlight and away from damp. Silk does not fade quickly, but it does dull with prolonged sun, and the board underneath warps if it is stored somewhere humid. A shelf, away from a window, is enough — and if a bloom ever flattens, reshape it by hand. Wrapped silk holds whatever curve you give it.
