If you like felted things this is the pattern for you! No washing mashine required - just a bowl with hot water and washing up liquid! I added trim to the sole to make them un-slid! BASIC SKILLS NECESSARY Stitches used: ch " chain stitch; sc " single crochet; sl st - slip stitch SIZING / FINISHED MEASUREMENTS 3-6 months " 10cm or 3.9 in 6-12 months " 11cm or 4.3 in 12-18 months " 12cm or 4.7 in 18-24 months -14cm or 5.5 in 2-3 years " 16cm or 6.3 in Sizes are approximate as you will be able to adjust them while felting. More your slippers are felted smaller they will be. That(tm)s why I suggest handfelting!
