I made one of these for my SIL's wedding. While the wedding ring pattern is very pretty, I don't know about trying that on for your first quilt, and I don't know how you'd do the signing.
What we did was cut out a bunch of squares. I used pinking shears on the edges so they wouldn't fray as much.
I would suggest you have a 'special' person at the wedding be in charge of this...we had people who do not sew sign right on the edge of the fabric--which makes it pretty hard to make any kind of seam.
The original intent was to simply sew the squares together, perhaps with a border between them. However, because of the writing on the edges, I ended up using fusible webbing (the double iron on type stuff) behind each square) and put it on another piece of fabric. I then zigzagged around each square. Then all the squares were sewn together. Only thing 'fancy' about this quilt--I did a bigger square in the center, and I used a t-shirt transfer to put a wedding photo in that square.
If you have any questions, pm me or drop an e-mail jesskcarl@yahoo.com I'm certainly not a super great or experienced quilter, but doing a simple squares quilt isn't too hard.
Good luck!
