No - it's not wrong. Is this the pattern? http://store.quilting-warehouse.com/087657.html

I made a brick quilt after watching their show. Did not need a template. Just cut strips at 3 1/2" then sub cut into 6 1/2". Masculine quilt for my son's birthday. He loved it. I used all flannel though.

If it is wrong, I do it too.

I was working a temp job back in Oct 2011 and one of the co-workers
was going out for a night on the town, so he went and purchased a new
shirt and I fell in love with that shirt. I told him it would look better in a
quilt than as the shirt it was made for.

I changed my mind very fast when he showed me the $150 price tag on
the shirt....... told him no way in heck would I spend THAT much for a shirt
much less for what would equal LESS than 1 yard of fabric.


That was the last time I looked at a shirt and thought "QUILTTTTT"


LOL

This is how I made my first quilt. I made hubby a shirt which I was not pleased with and it hung on the door for a couple of weeks as I tried to work out how to fix it - I had a light bulb moment - why not cut that one shirt up into little shirts and applique them onto blocks for a quilt. I just hate wasting fabric so this is what I did. That quilt is now referred to as "the little shirt quilt". It was made with an hawaiian print fabric and it is one of our favourites.

Go ahead and ask him - he may even offer up another shirt or to for the project. Let us know what happens.
