I just tried using 505 spray basting for the first time. I am so disappointed. This brand has been recommended on many posts/ topics by many people. I do not know what I did wrong but I found that I had to use almost a 6.5 oz can to baste a 70 x 90 quilt. I bought it from Connecting Threads for about $6/can since I could not find it locally. I may not use this again due to it seems expensive at $6/can per small nap quilt. I can pin cheaper even it it is not convenient when FMQ. Any ideas as to why I had to use so much? Other ideas?
