I am planning to make a baby quilt/floor mat type thing for a friend's baby but am not sure really how to do it. I don't want to do a patchwork quilt as I think it will take me much too long - the the baby is due now!. Also, I've got a large piece of patterned fabric that I'd like to use and it looks lovely without me cutting it up into pieces. I'm planning to applique some shapes onto it as well - I'm reasonably confident doing machine applique. However, I do want the mat to have the thickness of a quilt with batting in it, so I will need to use quilting techniques. Should I applique onto my top fabric first, and then make the quilt sandwich and use some kind of straight stitching? But how would that work with my appliqued shapes - it might look odd if they have quilting lines running across them. And how close/far apart should the quilting lines bearing in mind I want it to be machine washable?
Any help gratefully received!
