I'm building a lot more inventory, frequently checking where I show up in searches, purchasing extra yarn every time I buy supplies, and purchasing plenty of shipping supplies.
Some other things I've done all summer are to build my Facebook following, design all of my new products, put out some well-placed ads, & become established locally through shows and local businesses.
Other things you may want to consider are to make sure you have plenty of promotional material: business cards, product labels, promotional post cards, etc ready for when the time comes.
