I'm working on an envelope clutch for my friend Lauren, as a Christmas present. I've made clutches before, and although I love the way they look when they're finished, they're always so flimsy.
Since it's not for me, I want to try and reinforce it. I was wondering what you guys thought about using poster board or card stock between the shell and the lining. I thought it might work well to sort of "tack" the fabric to the board with sequins in random places. Is that a silly idea?

Here's the shell. The lining will be the same satin, but plain. I'm going to attach them like a pillow (inside out, stitch around the edges, then turn right side out).
Once I've attached the lining, I'll stitch up each side.
I'll use a snap on the inside to close.
On the front of the flap I'm going to attach this pin I saw at Gap. It was the inspiration for the clutch.
I was thrilled when I saw the pin in a magazine, because Lauren is buying these shoes from Delia's.
The pictures really don't do the satin justice. It is rose, the loveliest shade of pink I've ever found. I got a great deal on it in the remnants basket.
As an afterthought, I may sew some of this sequin trim on a matching ribbon to make a strap for her wrist. It'll be an extra-large wristlet.
