If they are tiny, after the quilt is washed, they probably won't show. Someone said they are called "kisses" for the person who receives the quilt. I like that... ;)
I wear gloves when quilting and it helps keep the fabric taut. I also slightly tug the area (gripping both front and back at same time) where I am going quilt to make sure it gets the fabric taut. Hope this helps.
As for walking foot, I wouldn't try it without it. You would definately have puckers then.
