If the project no longer "speaks" to you and is driving you crazy, then I would give it away! There may be someone in your local guild who would be delighted to finish this. If donating it is not an option, try turning the parts you have done it into something (bag, purse, tiny wall hanging) and use any left over fabric in another project. Sometimes in spite of our best intentions, a project just doesn't get finished. Every quilter has a few of those. I have just recently finished the blocks for a quilt top that were cut out when I was 16. I was going to tip all of those unstitched bits into the trash when I realized that they were a direct link to home and were pieces of my childhood. I've framed each block and will make two quilts, one for my sister and one for me!
