I don't believe in fancy tools I use what I have around the house to do things and I came up with this,
This is quick and easy and you can turn them to the right side in about a minute. I sew only 2 sides of the fabric right side together, then close to the botton on the opening I cut a little slit. I then take a crochet hook and push it down the length of the fabric inside the opening HOLDING the hook. the fabric gets all bunched up. I then put the crochet hook through the little slit and loop the fabric around it. I then pull the hook back down the way I push it up the fabric. as you pull it down the fabric is attached to the crochet hook and it goes right alone with the fabric. and now it is the right side. then I finish off both openings.
