I've been making quilter's trading cards - and having fun doing it! The size is 2 1/2" X 3" and instead of card to make them stiff, I have been using the new stiff iron-on bag lining. It works a treat, making the cards nice and firm (but not thick) and as a bonus, I can back the cards with fabric. This means that the message can be either written with a permanent fabric marker, or if you are industrious, it can be embroidered!
Why am I making these? Earlier this year, I joined the quilting group at our local community house. We meet once a month, with the odd "mystery quilt" day thrown in for good measure. They are a great bunch of girls - I seem to have so easily slipped into the group as if I had been going for years! Very warmly welcomed.
So that's why I'm making the cards - we are doing a trading card "swap" later in the year and we have to make nine. I hope mine measure up! (I suppose I'd better do some with bears on them!)
