Lots of good advice here about having your co-worker kept involved in all the purchasing of fabric etc. I have made 4 t-shirt quilts now and I really like using stabilizer. I use the most lightweight iron-on 'pellon' I can find and I iron it on after I cut out a larger than needed part of the tee plus I leave the neckline part on to help it keep its shape until pellon is on. Attached are pics of two of the ones I have made just to give you ideas.
