Hello Sherry
Welcome from Nottingham, UK - lovely to see more quilters joining us here. You will love it - just wait & see.
Now to answer your question regarding fabrics - don't laugh now but everytime my DH comes in from work & takes off his tie (he has an office related job in a hospital) I say umm that shirt looks like it needs replacing. He often raises his eyebrows, nothing quite like taking the shirt of the back of the person that feeds you LOL.
Anyhow listen to me rabbiting on - I now make sure I use his old shirts & my boys shirts too. I wash them, I cut them up remove the buttons & press the fabric. Ta Dah your be amazed at just how much fabric you can get from one shirt. BTW the shirts are all 100% cotton.
Go on get & have a good old root through the wardrobe LOL - Good Luck
Tisha :P
