Counted cross stitch can be a very fun and rewarding pastime. It's one of the few crafts I enjoy and that I feel confident about the finished results.
There are a number of ways you can mount and frame your finished cross stitch projects. Cost is always an issue. Frames and mounting accessories can be very expensive. I've found a couple of ways to cut corners that still produce pleasing results.

Frames are easy to find. I like frames of all shapes and sizes-they give your finished projects more character. I often bring them home with no particular project in mind. You can always save them until you need them, especially if they were cheap! One of the best places to find frames is yard sales. You can often pick them up for .35 or .50 each (compared to $5 to $50 at the store). Thrift stores are also a good place to look. When I'm pressed for time I pick up a $2 frame at Wal-Mart.

It's not necessary for your frames to have glass. Sometimes I frame my projects with glass in front of them and sometimes I don't. When I'm not going to use glass I make sure to spray the surface of the fabric with Scotchguard to help prevent future stains.

I mount my projects in two different ways. You can buy mounting boards in any craft store. There are two kinds-padded and not padded. I've found that the padded ones work great when you have a frame that doesn't have glass. The padding makes the fabric stand out from the frame a little and looks very nice. It's also easier to smooth out any wrinkles in the fabric.

I use the non-padded mounting boards when I use frames with glass. The nice thing about the mounting boards is that your fabric sticks to them so it won't move around after your project is mounted and framed.

I've found a quick trick that saves you from having to buy the mounting board (if you're using the non-padded kind). The back of your frame is usually a piece of cardboard much like the cardboard the mounting board is made of. I've found you can use spray-adhesive to mount your fabric directly on the cardboard back of the frame. It works great. You can buy two different types of spray adhesive: repositionable and permanent (it's never coming off!). I like the repositionable because you can still move the fabric around until you get it just right.

When I've got the fabric where I want it (after measuring to make sure it's centered and also cutting off the excess fabric), I use masking tape to fold over the edges of the mounting board. I get it as close to the edge of the board as possible on the front of the fabric, and fold the remainder to the back. This keeps the edges of the fabric from fraying.

Additional Tips:
If you get a little stain on your fabric you can often get it off by dampening the fabric and rubbing a bar of soap or dishwashing liquid into the stain and rinsing.
Before you place the fabric on the mounting board, iron gently to get out any wrinkles in the fabric. If you mist the fabric with water, even the toughest wrinkles will come out.

Using Scotchguard (stain guard that comes in a can) on your fabric is optional, but may help prevent future stains from ruining your artwork.
