I have one quilt on the go at any one time, and I finish it before starting another. I have a few random blocks mostly made from scrap pieces of fabric, and there will eventually be enough of these to make a quilt.
I can not justify buying loads of fabric for a 'large stash', it would make me feel ill. I make quilts from random but very pleasing, pieces of fabric bought in charity shops or repurposed. Very occasionally, I will buy anew piece of fabric for binding, or a border, if I cannot find anything to match from my box of treasures.
I like hand stitching, and I generally have something on the go, either red work, or traditional style embroidery.
Yes, pillows are for beds, cushions are for chairs; different shapes too
