I ended up writing up my own pattern because I couldn't find one that was exactly what I needed. Maybe one day I'll get around to typing it up into a tutorial or pattern. But I ended up with the exact perfect size for our bed.
The fabrics are Watermelon and Soft White Michael Miller Cotton Couture. Cotton Couture is delicious! So soft and silky. I HIGHLY recommend it! And even more awesome is that the red did not bleed AT ALL! I was so scared putting it in the wash, I put 4 color catches in and there wasn't even a slight tint to them when I pulled them out of the wash.
I took the quilt Eagle Mountain Quilting for computerized long arm free motion quilting, the design is called Cotton Candy. I love the curvy texture against the very geometric design of the Irish chain.
The backing is Michael Miller bleached denim, a goregous light aqua shade! It makes me so happy!!
The quilt finished at 93" square (it was 96" pre-washing), and was made with Hobbs Heirloom 80/20 Batting.
