Here on the QB are 2 recent mystery quilts. The Mystery Train ride #8 & 9 are both scrappy. Since they are finished you can see what they will look like finished. Some have made them larger to fit beds, others have made them smaller for wall hangings. They also finished them differently with different sashings and borders. Which anniversary is this? You might want to incorporate that into it somehow. The lone male quilter in our group made his wife a wall hanging for their 5th, I think. He looked online and found that was the year for stone, like 25 is silver. He used the Stonehenge fabrics to make the wall hanging. You might go with a predominant color or something like that. Ours is going to be 35 this year so it would be ruby.
