* Sunshine's theory on needle size:

1.    If the floss can be threaded without a  lot of difficulty and the needle does not  slide off the  floss when dangled - you have a good size to work with. 

2.    If your floss becomes frayed after stitching for a short time - try the next size larger needle. 

3.    When working with a thick floss, the needle is your tool that spreads the fibers first to let the thread pass thru easier.

4.    If the thread consistently becomes loose of the needle - try using the next size smaller needle.

5.    If you can see the entry or exit hole of your needle after stitching - you are using too big of a needle.

6.    Since the needles do not come with an imprint on them stating the size, it is best to create a way for you to keep the sizes straight.  Something as simple as marking a piece of fabric with the needle sizes and making sure that you replace that size needle in it's appropriate place works.  One stitcher told me that she uses a different "Needle Nest" for each size needle.  There are many needle keepers that can be purchased or made but I use the above guidelines if I am in doubt.
