ok so it has been a few days and my needles have harden up quite a bit, they went from being totally flexible to barley at all. Also I wasn't able to push them out and had to cut them out. but I feel if I was to sharpen them to a point now they would be useable, but I have never knitted so I have no clue lol.

I'm not sure if it was already mentioned but...

It seems to me a grinder that is used for grinding glass (stained glass pieces and that sort of thing) would work as glass is best ground wet too.
Also, did you put the yarn into the resin first or into the straw and then pour the resin in?

Very cool...thanks for the tutorial!

My mom just got me a jewelry grinder that's perfect, but I can't use resin and glass on the same stone because the resin heats up and leaves resin on the stone that deposits on the glass.
 So as soon as I get my glass grinder I'm not touching it with resin, but I imagine it would be perfect, if I had 2 grinders!  but the regular grinder with a mask works fine in the basement, made life much easier.
 Then again, maybe being wet will keep it from getting hot enough to stick to the grinder? I don't know, I don't trust the resin that much, I'm sure I'll check and see though!

I also used envirotex lite pour on.  The straw still does not make a crinkly noise and i can't push the resin out of the straw (4 days later).  I did cast a couple other pieces.  The thin ones (1/8-1/4 think) will soften just a bit if carried in my pocket.  Enough that I can bend it.  But when cool is quite hard.  The straw seems to bend just a bit also. 
I feel a little better knowing I am not the only one having trouble Cheesy

epoxy resin does that sometimes, I've made bangles I never realized would bend, and then took them to an outdoor summer craft show, and they sat in the sun and got well, bendy!
 Pretty sure I've read that's a normal characteristic of epoxy, I know for sure I've read that f you use it to coat a table/bar etc that t can get a depression-ring-mark where you set something on it, and it'll go away within a couple hours.

Oh-wow-smashes head-on-desk-moment, the epoxy resin may definitely not harden for this project... I just put it all together as I was typing that, yeah, epoxy resin may definitely not work for this, at least for thinner needles. I still haven't cast my epoxy test needle, I ran out of straws!
 
I wish I'd known that at the beginning, I'll go make a note at the beginning of the post.

Here is my result from my first try at this (and my 2nd try at resin, ever).

Yes, that's a giant air bubble.
See?

I had to cut the resin out of the straw (I used an x-acto knife).  It seems pretty firm until the heat of my hands warms it, then it becomes pliable.  I found I can sharpen it with a pencil sharpener though.

I didn't sharpen it all the way though because I don't see it being much use as a knitting needle or as a hair stick if it gets all bendy while holding it.
I'm not sure if it's the type of resin (epoxy) or just the brand (EnviroTex) that is the cause for the warm=bendy problem, but I would like to try this with a polyester resin (and try different techniques to keep the giant air bubbles out.

ETA: Yay for posting at the same time!

Guess I'll be getting that polyester resin after all!  I'll use the epoxy resin to learn what the heck I am doing!  Grin
I wonder if you could cast the tip in epoxy so you can sharpen it easily and the rest in polyester so it doesn't bend when warm...

It should harden just fine, but lay up resin is usually painted over, so often it's not clear, something about making it easier to see while people are working with it,  say on their boat, and smoothing it out I guess. I googled a few lay up resins and some didn't state the color, and one said it was dyed red. So I would make sure what color it is, assuming you want clear resin to play with, but otherwise it should be about the same.

That's a crazy bubble!
 I suspect the epoxy resin is thicker that the poly I'm using, and so it's not going into the straw as quickly. Well, I know it's a bit thicker, but I suspect that may be why it's harder to get it into a straw. Another thing I had no idea would happen!

I'm getting straws today, so I can finally cast an epoxy piece!

The epoxy will work well with jewelry molds though, or if you wanted to cast epoxy toppers separately. Last week without realizing it I poured a little extra poly resin into a mold that had epoxy resin in the bottom of it, and the 2 pieces separated after it was cured!
