I think 1 1/4 or 1 1/2 yds for each hamper would be enough...here's how I figured it: (I'm assuming the lining will be shaped like an open paper grocery bag? i.e. 4 sides, bottom, & open at top?) Hamper #1 you need: 2 pieces 18x19 (large sides) 2 pieces 12x18 (smaller sides) 1 piece 12x19 (bottom) At 54" wide you can cut 1pc 18x19 & 2pc 12x18 across, then below that you get the other 18x19 and 12x19. So the length you are using is 19+19=38...round up to allow for seams, etc therefore about 1 1/4 yds (45in long x 54in wide)should be adequate for #1. Use same method for hamper #2. Hopefully someone will check my math. Also, if you are going to a fabric store, they will help you with yardage and layout. Good luck!

Depends on what need a lot more info than above.

I've tried to find them--when I search I get design firms that have access to their products--its a TO THE TRADE-hence my reaching out to Houzz people. This is an English or Australian manufacturer (from what I could find) so not easy to contact.

@Indecisiveness, no, because our last house burned down in a wildfire and we are currently in a furnished rental. I have taken extensive measurements of the space and used planyourroom.com to make sure the furniture will fit. @mcbmd3 That's exactly what I'm looking for - thank you! I googled around and I was using the wrong terminology in my initial searches. Turned out I needed a "white glove receiving and delivery company." For anyone else who is looking for this kind of service.
