I think muslin would work. Iron 4.5" x 4.5" pieces onto freezer paper before the shower so they can write on them easily.

Since she is having a Fall wedding have you thought about using a leaf pattern for the blocks? You could do an inverse color with the leaf in muslin for signing and use Fall colors for the surrounding parts. Picture attached in case that doesn't make sense. The Maple Leaf pattern is available on Quilterscache.com.

If you give them plain fabric to write on, be sure to pencil in around showing the seam allowance. Otherwise, someone is likely to write right out to the edge of the fabric.

I agree that muslin would work fine. You can look for a high quality muslin that's a little bit thicker.

You could do something along the lines of a double/triple Irish chain with the signature blocks alternating. Or a 8 or 16 patch block alternating with signature blocks.

This is a nice block for signatures. The block pattern is free at Quilt In A Day. Could make them in the wedding colors. Lots of possibilities.

I have done a similar idea using nine patch and snowballs, The snowball block is the signature block. They were made up beforehand so all folks had to do was sign them And they were ironed to freezer paper for stability.

I have always used a good quality muslin and it works well. I have also used the signature blocks as the backing for a wall hanging I embroidered for a small wedding. Fall colors will be pretty and any block with white spaces will work.
Drawing the frame is a very good tip and also have something like a clip board than they can lay the block on to sign it. AND have extra blocks, at least 5 of mine were do overs.
It is a great gift idea, looking forward to the pics!

One of my friends is making a signature quilt for her son and his wife-to-be who will be married in October. Here is what she is doing:

~ she bought a light batik fabric, cut squares, pressed on stabilizer, used a decorative stitch to outline an area on the square where the wedding guests are to write

~ will take the squares to the wedding reception and pass them out to the guests with Pigma Pens for them to write words of congratulations, advice, sentiments, etc. during the reception

~ she will have a display board set up with sample blocks written by her family members

~ the quilt will be made and given to the couple after the wedding; a batik border will be added and any other elements that the quilter wants to add.

This weekend she made a small wall hanging to give to her son and new DIL as her gift to them since the bed quilt will not be ready.

So many great ideas! Thanks, guys :-) Since the shower is on Saturday and I'm very busy up until then, I'll see what I can get done since I'd like to have some squares ready for the shower guests to sign. I'll let you know what I end up with.

Thanks again!
