Where did the drapery fabric come from?

She fails to understand the point if Houzz and feels too threatened "to reveal her sources" thinking people wish to copy her exclusive designs (ROFL), so is using the site merely for free advertising. Very insecure and won't even share a paint color.
I specifically ran this search for "striped curtains" for a project to create a traditional big-top-circus theme for a child's room and these would be perfect!
They are available at:
Half Price Drapes
On etsy at kirtamdesigns
IKEA (material)
Cafepress.com

I custom make drapes and have made some similar to these pictured. Tie backs can be made as well.

@gh4u on the other hand, the designer stated that the chairs and sofa are vintage, which means the pieces were purchased a long time ago and or 2nd hand, therefore, she is not giving a source/store to purchase from because the pieces would most likely no longer be available. Maybe she purchased the sofa from a garage sale, would telling you that help you buy the sofa? I think not, thus she used the word vintage assuming one would consider the aforementioned.

Also in her defence, she does answer many questions. #beakindhuman

Check out your local newspaper, 2nd hand furniture stores, Goodwill, or online Craigslist or Kijiji for some great vintage finds. Also be careful to inspect the furniture, take a small flashlight and pull back seams and or piping/welt and inspect.
