That is so timely! Today I was going to do something similar. I tried to use liquid starch in a spray bottle to baste a table runner I'm making, but the nozzle must have been too small. I'm sure I've seen starch in spray bottles, so I'm going to try to find it. Otherwise, thanks to your post, I know my idea is possible, and I can just use the aeresol can like you did. Thank you so much!
