I haven't done any felting in months but when my dad e-mailed to say that mum needed a cover for her birthday Kindle I offered to make her one. I was surprised to discover how small they are, smaller than a book, a mere 19cm by 12. Felting something down to a precise size is no mean feat. I allowed nearly 50% shrinkage and then made a cardboard cutout to judge when it reached the right size. I hope it fits.
