To Walk or Not To Walk?

I discovered the answer to that question yesterday when I attempted to sew a bag without my walking foot.  The sewing went fine with the wallet, but doing the top of the bag was extremely frustrating (close to impossible!) and the whole thing turned out all slanty.

So to add to the post about the Shark people--yes, turning the screw helped a lot, but getting a walking foot that was not missing a piece and worn out helped even more. 

I should get a picture of that little thing on here...
