My last post was about mug rug patterns...well, I found some cool material and put some together and thought...I should try FMQing this. So I took my walking foot off...and now what? I can't FMQ with the regular foot on, but when I take it off there is no stability. I have to have a foot of some sort...but what??? I did drop the feed dogs. I tried every foot that came with my machine, but to no avail. Do I need to order something special? Help me, please?
