YES i do use them I have a large box of them from way back when (when they cost 19 cents apiece ;)...my granddaughter who has decided she loves to embroider has borrowed a couple of them from me. my first (real quilt) we call the picnic quilt has redwork blocks made from one of these old patterns, it's called love beneith the willows and has animated dishes...so cute! i really need to snap a picture of that quilt...
when i get one out that doesn't transfer i just use a transfer pencil and trace it, then it irons on just fine for 5 or 6 times usually.
