craftgrrl | can you please help me... thread recommendations

I am going to buy some thread or elastic for some lightweight trinkets I am making - basic beads - nothing too heavy.

I am looking through the list of products and I have googled for more info - but I know its better to find out from people who actually use the stuff and have had experience with it...

The items I am looking at are

~*~ Stretch Magic
~*~ Nymo
~*~ Superlon thread

If any of you can give me suggestions as to what you thought of any or all of the products I would be eternally grateful.

As these are for fundraising - I dont want to waste money and I dont want people to buy things and have them fall to bits in a week - I want everyone to be happy...

Thankyou again for reading this, and have a great day :)
