More SuggestionsFigure H - Use a notebook for holding those extras and for keeping those pesky circular needles out of the way. Keep the needles in plastic insert sheet holders, and put hook-and-loop tabs across the top to hold them closed.
Figures I, J - Or put the needles into zip top bags. Punch holes across the bottom to fit over the notebook rings and keep the top facing out. Write the size of the needles on the bag with a permanent marker. Note: To make it easier to punch the holes in the plastic, hold the plastic over a piece of an index card or any lightweight cardboard and punch through both at the same time.
Figures K, L, M - Cover a coffee can with self-adhesive paper, put some unpopped popcorn or uncooked peas/beans in the can and stick the needles in. To eliminate the sight of the ridges on the coffee can, cut a piece of paper (watercolor paper is good) the exact size of the can and cut the adhesive paper 1 inch longer. Peel back only the 1-inch extension. Stack the two together, wrap around the can, and secure with the sticky extension.
Figure N - For longer needles, make a taller container. Cut a piece of poster board large enough to go around the plastic coffee can lid and twice as high as the can. Cover with self-adhesive paper plus the extension. Roll into a tube using the lid as a pattern for size. Secure. It should be just enough larger than the covered coffee can to easily slip over it and cover the extending needles.
Figure O - Use an inexpensive vase from the florist, partially filled with the glass flat-backed marbles, and insert needles.
Figure P - Leave the needles in the plastic holders they came in and slip the holes at the top over a large notebook ring. This can hold all of your crochet hooks and stitch holders, etc., as well. Hang it on the wall, on the back of a closet door, or under a work table. It's probably the least attractive but most convenient way to store all of your knitting materials together in the smallest space.
