Thanks for the suggestions. My machine doesn't have the ability to lower the pressure on the presser foot, so that option is out. I wish I did have that option because a lot of what I have read suggests that. Adding more quilting lines at 1.5" like someone suggested might help hold things down too, I just prefer the look of less quilting. Guess it might be a trade off I have to make. I know the puckers will hardly show once it is washed, but they still bug me! I just felt that it was for sure a basting issue since some seams were laying perfectly flat as I crossed them and others 'stood up' a little. Does anyone have any tips for spray basting, especially when adhearing the top? All the tutorials I read give great detail about spreading the back taut (which I think I do well) but not much give details about spreading the top.
