Definitely the above, pins, extra rotary blades. The 6 x 24 ruler you can get at Joann's with coupons or Walmart. It may be your over $20.00 along with your cutting mat. A good rotary cutter is gonna cost about that much also as well as the extra blades. Pins, fabric, seam rippers will be your under $20.00 items.

I have a seam ripper but don't know where it is as I use a small pair of scissors when I need to remove stitches. Look for the cheaper items at places such as Walmart, Tuesday Morning, yard/estate sales. Look on Craigslist for yard/estate sales as you can get some wonderful items there including fabric.

While quilting is not an inexpensive hobby, you can build your inventory over time and spread your purchases out. This way you do not realize how much you are spending on this craft. Don't consider purchasing specialty rulers until you get a feel for what you like and will use. I only have square templates that I purchased and got a flying geese one in a swap. Otherwise I make my templates with template plastic and cardboard. Just about any shape of template you want is available for free online. Downline and make your own templates.

About the iron, some use really cheap irons and some use expensive ones. Start off with a cheaper one and as you grow you can determine what your needs are and what you like better. Enjoy your new hobby.
