Table Loom Weaving

I did weaving many years ago - have just looked at some of the sites selling the looms. I would not go for one which is very low on the table as it will severely restrict the length of fabric you could weave - you might want to do large pieces when you get into it.
The thickness of the warp will depend on the hole size the things on the heddle allow ( can’t remember the name). Also if the heddle is deeper and has more than one frame it will allow more complicated weaves as you progress.
Also the shuttles need careful choice due to wool thickness possibly restricting the amount of wool you could wind in them.
Good luck with a new adventure.

I use an ashford loom. I think it's an old one as I was given it by a kind lady whose elderly MIL used to weave.
It's 4 shafts and I believe table top. I am still learning and just weave scarves with DK wool

I also have an Ashford and also make scarves from dk. I have a smaller portable loom I cobbled together from an old canvas art frame and nails. I use that to make more arty things like wall hangings where I experiment more with different textures and rya knots for fringing.

I have a Louet table loom and love it. It is simple, sleek, functional and works beautifully. It’s small and tidy and will sit on a table but it can also have legs as an extra if you want. I have legs on mine and use it that way but if demonstrating somewhere I would usually just take the loom part.

The chunky old-style Harris table looms are indestructible- most schools/colleges and universities will start students off on these for good reason.

I have woven extremely long (fat) warps on these with no problem. Also, you may be lucky and find one with a second back-beam which extends what you can do with it.

Here’s somewhere else to look for second hand looms if interested:

Re size, the heddles (which you thread with your yarn) are plenty big enough for any yarns you have been knitting with so don’t worry about that. I’ve never seen a loom with small holes in the heddles and have used maybe a dozen different ones now.

Re dents per inch - the only 2 looms I’ve actually bought rather than used elsewhere came with reeds that would take pretty thick yarn. DK and Aran wouldn’t be an issue certainly. As a weaver rather than a knitter I’m not sure how chunky you mean... but I did use a weft yarn that was nearly 1cm diameter last year for one project - but this WOULD be too fat for the heddles!

Regarding books.... My absolute favourite is:
A Handweaver's Pattern Book by Marguerite Porter Davison
I think it’s been reprinted. Mine is a 1950s version and was the one book above all others that helped me understand the principles of weaving. BUT you MUST read the intro and not just dive into the patterns.
I know there are more modern books out there but the black and white prevents confusion between weave structures and images and I would recommend it to any beginner.

I have fallen in love with weaving. It is THE most glorious, uplifting, frustrating, amazing and meditative thing to do!
Good luck... DM if you want to chat!

PS the “shed” is nice and wide on the Louet
