I am tring to make a purse that I ordered the pattern from the internet and much of the pattern calls for two sided interfacing and when I tried to sew through it with my machine it gummed up the needle and thread, so I stoped for the night and am soo frustrated .Has anyone else come across this problem? Really would like to applique with it but am afraid that over time it would come unfused and not sure where to go as to making this purse as it has many pockets that also calls for fusiable interfacing.PLEASE HELP.
