Living fence using willow...options? Is using weeping willow feasible?

Hi! Brand new to the forum although an intermittent lurker forever. Figured this is the best place to ask my current question (I'm relatively new to all things permaculture as well so I have lots of questions!)

I moved to a new house last year and have been desperate to screen off my direct line of sight to the very nosy neighbors across the road who are very very confused that I've let things get so "overgrown." I think my best option is a woven willow fence, in terms of fast-growing and aesthetically pleasing, and something I could even potentially trellis other things on. It's far enough from the house and septic that I'm not worried about roots. However, looking around online for suitable willow rods to get it started this spring looks pretty pricey...with minimum orders, $400 or so. The house does have a giant *weeping* willow, which I could take cuttings from freely. Would that even work? I'm willing to cut it back every year in exchange for being...well...free. I can also presumably stick smaller cuttings which are of course much cheaper and weave them as they grow...I love the head start of starting with longer woven rods but finances are always an issue. Thanks so much in advance for any experiences/ideas!

I recommend finding a local willow patch of trees that grow to a modest height. Harvest your cuttings from that. Weeping willow trees turn into massive trees that might create problems in 20 years.

I think San Francisco was ringed by willows planted 12 " apart  I believe  as a defense from starving cattle.

Yeah, if I could find a local source of non-weeping willow to harvest I totally would....I just haven't been able to find any. I'm always checking roadsides!

Black willow grows along streambeds around here. I think that would be a good place to look. It also gets huge if you let it... Pussy willow might be the best thing if you can find it.

Many people say to simply coppice or pollard in the dormant wintertime.

Hey-ya, so I have been working on one and here's what I found:
You're gonna need non-weepers, just cause it gets heavy and has to maintain the shape while it gets established. The rods are usually 4-5 ft and a weeping rod will bend at that length. Also finger-thick, weeping rods don't get that thick. Honestly any other random willow will work.
Definitely do not buy them!!! Is there a park with water handy? state game lands?
For best results put cardboard on the ground first and poke holes in it. willows hate weeds, esp if they're not getting enough water. Cardboard ill hold wetness too.
Or you could use Red Osier Dogwood, which is borderline invasive in my opinion. Also roots if a cutting is placed in the ground.

Making a living fence/hedge is a great idea.

Red Osier Dogwood "borderline" invasive? It takes root wherever a branch tip touches ground, and will sprout from any piece left in the ground. Great if you want a thick hedge, as long as you keep both sides mowed, otherwise it will spread until it hits pavement or forest.
