If you have the kind of festive gathering at which people like to wear paper crowns, you might consider making your own.
Making the crowns is especially easy if you happen to have some Post-it notes in different colours. (I have a stack that has been sitting, unused, on my desk for so long that the lettering on the plastic label sun-printed onto the top Post-it.)
To make it easier to keep things in a straight line, print out the Crown Spacer, or draw your own. The distance between the vertical lines should be half the diagonal width of a square.
Place a Post-it diamond-wise on your spacer, with the glued edge sticky-side-up on the upper right. The top and bottom points should match a vertical line. The right hand point should lie on the horizontal line. Place a second Post-it on top of the first and to the right. The top and bottom points should match the second vertical line, with the right hand point on the horizontal line. Continue adding Post-it notes until your crown is long enough to fit around the head of the person it is made for.
Score a horizontal line across all the squares and fold the bottom points up to match the top. If you have worked fairly quickly and don’t live in a very dry climate, the glue on the Post-its should be sufficient to hold things together. If the glue has dried too much you can use a glue stick to make things hold together.
If you want your crown to be bilaterally symmetrical, make two shorter sections. The sticky strip should be upper right on the right-hand section, upper left on the left-hand section. Use a glue stick (or double-sided tape) to join the two sections. On the sample below, glue was applied to the orange square where the pink smudge is located.
For a more finished look, add a band. A band also means you can make a crown that just has points at the front. (If you are joining strips of paper to make your band long enough, make sure none of the joins end up at the front of the crown.)
If you don’t have Post-it notes lying around, you can cut squares of paper —Post-it note size is 3 x 3″ or about 7.6 x 7.6 cm— and attach them using a glue stick.
If you really hate gluing things, or don’t have a glue stick, you can make an all origami crown like the one below by following the instructions found here.
Either of these crowns would be suitable for the Bean King at Twelfth Night.
