To all the quilters who asked me about info for the boxes:
Here on the QB is where you can find the tutorial for the boxes with the french seams "Fabric Boxes with French Seams Tutorial" - a post from Feb. 2013 and the main box tutorial for the box itself can be found here "http://seaside-stitches.blogspot.com.au/2013/03/fabric-box-tutorial.html" and I make mine 12 1/2" and the sides either 2" or 2 1/2"
Good luck and happy quilting - looking forward to see some of yours!!!
