I've been wanting to ask this question for sooooo long but haven't because I've been a little embarrassed. I started using my walking foot for piecing a couple quilts back because with my regular foot my top fabric always ended up getting pushed a little at the ends. I thought the walking foot was like a crutch and that I just wasn't skilled enough to use a regular foot for piecing. Come to find out now it's a pretty common practice and I'm not alone! I feel so much better now! :)
