Machine Knitting - Needle Stopper with a Pool Noodle - LK150 - Brother - Any Knitting Machine 

You will really like the machine. Hope this tip helps!

I'll check it out. Might be too soft to hold the needles in place, though.

Mostly, I'm learning from youtube videos. There was a knitting store on Glenside, PA but they closed a few years ago. A machine knitters group met there once a month and I saw ths LK150 in work. I purchased a few machine knitting tools from a person in Bucks cty. about 3 years ago, but can't remember who that was. She gives classes, too. I'll get back to when I find the contact info.

i bought mine from the Lion Brand website 4 years ago, price was about $399. I think the machine is a higher price now.

Look for a dealer, they will give free lessons. AllBrands also sells the LK150.
