joy of quilting: priceless[/quote]
Yep! Agree.
If you can make do with what you already have, then besides fabric and batting, not much. If however you don't want to loose interest because if you are like most folks and want some type of instant gratification, the 'sky's the limit' according to your budget.
Be a savvy shopper, sales are good, you don't need all the gadgets, choose your projects carefully, don't hoard fabric, you buy what you can afford and what you have room for, and then consider the cost of therapy and drugs to keep you sane if you don't have quilting or some other hobby, PRICELESS.
