In Threads #131, then Senior Editor Jennifer Sauer, says to “consider jersey’s care instructions, then disregard them and start experimenting. The aim is to machine wash and dry your finished creation,” I washed a 4×4 piece of my 100% rayon jersey and it did shrink quite a bit. So I made a shirt without washing it and plan to dry clean the garment. However, I have more of this fabric and would like to use it for a child’s dress. Advice on washing 100% rayon? Thank you!
