I've been working with the CT tissue box cover pattern and have discovered that the front square needs to have a bottom border added, or the square needs to be 'rectangular'. The measurements given are sides and lining 5"X5 3/4"....yet the front panel is 5"X5", no matter what you do you need that little extra on the bottom of the front panel to be able to turn a bit under for the hem. I've been adding a bottom border and it works fine, but thought you might want to correct the pattern for future users.
p.s. the 'Quilt With Us' idea is great, I know it is a lot of work for the staff, but it is a wonderful service. No wonder we all think CT is the BEST THERE IS!!
