Attaching a Penannular
First raise the brooch up and away from the pin.
Then direct the pin sideways, and away from you, and gently wiggle
it through the fabric( pin going between the weave, not tearing
it). Scrunch the fabric as far as possible into the fixed end
of the pin. Next, lower the brooch to the fabric and have it go
under the pin. Then, with the pin at the outside, twist the brooch
in towards the pin as far as you can. The pin should be somewhat
perpendicular to the brooch. The more fabric you gather within
the pin, the more secure it will be.
