I love to read - even on the web!
Some sweet quilter wrote (someplace on the web) that if you have a few blocks that are off color or otherwise are less than perfect, go ahead and use them on the outside edge of your quilt. See how many are the correct size, see if you can't add to the small blocks and then put them on the outside edge. Trim down the ones you must.
Never tried it but I do think it might work!
