Luv to Quilt is right.
Do you two have Walmart in the cities as they sell the StaFlo liquid concentrate?
You will be amazed at the difference in seams, how your work lines up, it is just easier to work with the fabric, even cutting seems to be more accurate as fabric isn't slouching all over the place with wiffles and drubbles. Sorry, Cindy speak.
Good Luck
