I need an easy quilt pattern for a graduation signature quilt, for a full size quilt, also need yardage amount .

How about making a center medallion 20 x 30 inches in 3 inch strips sewn together with seams going the width of the quilt for the signatures. Do this in 2 or 3 pastel colors, then surround it with squares to complete the size.

Rail Fence (3 rails) would be nice and easy. Could even do it using up you scraps (but the center would be white/neutral)

I am making one for DD. Instead of having a "Guest Book" she wanted a signature quilt. We (I) will be making them in her colors (silver & sage). But she had found one online that the rails were different sizes (2", 2.5" & 3"). Here is the what I work out on EQ6.

thanks for your suggestions, will try it.
