Wow! Thanks for these tips. I've usually done the freezer paper on the bottom, basting the seam allowance to the freezer paper and then basting the piece to the background method. But it's so time and energy consuming! I've lately started gluing the pieces to the background and machine sewing the pieces to thin interfacing and turning the piece inside out. I'm going to see if I can graduate to needleturn with these tips, to save time and my poor thumb.
