Well my SID is not perfect, specially when I'm tired. LOL
First, slow down until you get the hang of it. I have the SID foot on but I don't really follow
the guide. I prefer to follow the needle. It takes a little while getting used to it but I get
better results that way. Slow down even more when you cross a seam that's where it
tends to veer off. But don't worry too much about it...just have fun. Once the quilt is
washed you won't notice all those mistakes.
