I have bought those pre made Hugs'n Kisses Fusible Paper Hexagons that are cut from fusible applique paper, you fuse to the wrong side of your fabric, cut and sew your hexies as usual, but leave the papers in your project, they will dissolve into soft fibers when washed, and can remain safely in your projects. I am asking for product sugestions/advice on ideas once you have turned the fabric over to the back how to stick down the edges ready for sewing together.

I do have some ideas myself but thought to check it out with TQS forum and see if there are any better ideas than mine.
