I went to a church rummage sale recently and bought two ziploc bags of rick rack, bias tape, and seam tape for $2 per bag.
I sorted the all-cotton from the synthetic.
Remember when stretchy lace seam binding/hem tape came out? And iron-on hem tape? (Fusibles have come a long way since the late 1960's.)
There were many unopened packages in the lot.
These are Coats & Clark.
Several generations of Wright's. Did you ever send in three labels and .10 to get "a generous package of trimmings suitable for doll's clothes"?
Winsome Lady is brand I hadn't seen.
Boiltex was made in Aurora, Illinois. The company was Creed & Stewart.
Some of the Trimtex is marked Milford, CT., and some Williamsport, PA.
J. C. Penney store brand. There were no Penney's stores in Chicagoland when I was growing up, but both the stores in Brenham, TX, and Pittsburg, KS, had dry goods departments in the late 70's/early80's.
I don't know Nynco, Warren's, or Just Rite but of course Fruit of the Loom is familiar.
Tidy Trim from the Williamsport Narrow Fabric Co. (Similar to TrimTex?)
