For those of you that responded to my basting question, thank you all, and lots of good tips! I am going to try the spray, it sounds too good to be true! My last questions is...... after spray basting, is it necessary to also baste by hand? If not, how long will the spray last? Sometimes I will start a quilt, and then get sidetracked with other projects and not finish it for a while. I also take my quilts in the rv to work on while travelling, which means they get tossed around alot. How much faith do you all have in the basting spray lasting without basting by hand in addition to?
