Update: I took some pity on Katrina and did a little more research. See below! –Mary T.
“I’m itching to make some lampshades using felt, but need some frames!” says Katrina. “I’m looking for just a simple, elongated cylinder frame, or a drum-shaped frame, and came up empty handed. I found lots of Victorian frames that do not lend themselves to the modern design I am looking for.” Katrina wants a frame that looks like the images above. So how about it, readers? Can you shed any light on this subject?
Update: Some possible solutions after the jump — click to see them!
Would these top and bottom wires from Fogg Lighting work? Fogg Lighting also offers an oval design which is closer to what you’re looking for.
Lamp Shop also offers wire rings — possible to use those to create your own form?
It looks like you’re looking for a cylinder design, but this page’s square frame from Hannah Murphy Lamps & Lampshades is pretty simple and could feel clean and modern.
Lara Cameron design has a nice tutorial on making a lampshade, and she mentions getting her supplies from Australian company Handworks. Alas, the Handworks Supplies website is no longer online, leading me to think they may not be in business anymore, but their phone is still listed online — perhaps worth a call?
Duffy London has a modern-ish make-your-own lampshade kit. Not sure it could be retrofitted to what you need, but possibly?
And of course, we welcome reader help as well!
