Yes, most definitely Yes. The worst thing is, it is really crippling if you allow it to be. I recently made a rail-fence for my eldest son, I fretted and fussed over it like you wouldn't believe, washed it twice (to make sure it didn't fall to bits). Was devastated when I discovered one of the fabrics was not as stable as it should have been (couple of seams needed a re-stitch. Worse, when I gave it to him I was apologetic, which he couldn't understand because he really loved it.
But the power of this board is strong....when I feel doubtful or unsure, I come here and get encouragement, tips and lots of help from this quilting family. There's inspiration by the bucketload and huge dollops of commonsense. No way am I letting my negative self get in the way of my love of this craft and my desire to quilt 'til I drop. So thanks for this thread David and thanks and Merry Christmas to all of you.
