I always felt attracted to pictures of cute footwear for  babies. I decided to make one pair and find out for my own how they turn out to be. I brought out some left over wool yarn I had and used 3.5mm crochet hook. The instructions for the pattern can be found at  http://thislovelylife-blog.blogspot.in/2013/03/todays-crochet.html .   The pattern source and my experience for the dress made can be found at  source .   You can change the number of stitches to reach the final sole size of 3.5 inches.  Enjoy crocheting!!
