As Jan has said these item are very inexpensive. You may also want to go over to the Knit Tips & Tricks
thread to see what you already have at the house for these items.
For example I use the little pyramid like erasers, that you put on wooden pencils after the original eraser if gone, as point protectors.
You can take a chop stick, cut is down and sand the end or use a pencil sharpener to give it rounded ends and use this as a cable needle. I have used paper clips as cable needles.
Take the second chop stick sand it smooth and make the ends rounded. Slide the chop stick through the stitches and put a rubber band on the chop stick from end to end to make a stitch holder.
You house if full of knitting tools that you just haven't found yet.
