I have said this before and will continue to because It is one of the best things I have learned to do that has improved my piecing.
Elmers Washable School Glue is wonderful for holding bias seams in place for sewing. I also use it to hold intersecting seams where I really want points to match, long seams, attaching binding (especially bias binding). It is a great sewing tool.
As for string quilts or any paper piecing, which I love to do, starch the fabrics well, remove the paper after I finish a few blocks and starch the blocks again. It is such a chore if I wait till the end of making all the blocks. Doing it a few at a time is much easier, emotionally.
So sorry for all the trouble you encountered. Keep seeking easier methods and never give up!
peace
EDIT: Taking the paper off before sewing blocks together has never been a problem and with string blocks, if they get a little distorted due to stretching, just trim them back to size, no problem.
