Some notes:
1) My machine was skipping stitches.. and finally figured that I need to change my needle. Replacing the needle solved the problem.
Read more here for potential reasons why the machine may skip stitches:

2) Thread
I was trying to learn more about thread and found these links useful:
a) Sewing with the right thread - gives an overview of different type of threads available:
b) This link has microscope view of various quality thread. The low quality ones, the thread has lots of loose fibers:

When I bought my sewing machine, the shop person said I should use good thread and they recommended Dolphin - buatan Malaysia (what they sold in the the shop). I have never looked at what it is... until this morning.. lol. The label said polyester and "D" and a number on the spool. I guess the number is the colour number system of Dolphin. What thread do you use?
Check out the various type of threads available on this site just for our knowledge. Luckily I didn't know there are so many choices, otherwise, I would be so confused to start with so many.. :)

This one is interesting.. - Water Soluble thread! http://www.sewessential.co.uk/Category.asp?CategoryID=1339&NumPerPage=5&page=1 It is for basting... but if you use it accidentally to sew cloth... the cloth will fall apart while you wash it.. :)
Bye now,
