I believe in quit fairies. They are cute little things covered in odd pieces of tiny scraps of fabric and those little snippets of thread we toss aside. Mine tend to be mischievous little creatures but not at all destructive or mean. Frankly, what they think is a \charming little trick is frustrating and time consuming to the human quilter. My best solution curtail their activity is to ignore the quilt fairies altogether and they will eventually give up and your missing item will reappear when you least expect it to. Often under the pile of fabric you just looked at or in the basket you just dumped and sorted twice before while searching for your lost item. On the up side these wee ones also will whisper in my ear "Dearie, you can finish one more block before going to bed", or "You can do it, it's not that hard" and 'Wow, that is beautiful!"
