I love that fusible interfacing can help to structure a project that needs it.

Thank youuuuuuuuu!!!! I've wondering why my old but beloved shirt collars and cuffs bubbles, no more iron on interfacing in those areas

This is so helpful! Would you have any tips on applying knit interfacing for stretch fabrics? I'm looking into sew on and/or knit interfacing because the sweater I'm upcycling stretches as I sew. Thank you!
