Most knitters need to use markers when knitting. One of the easiest ways to do it is to use threads. They will give a lot of information while working. Here are some examples of the simplicity by using thread markers.
First, the threads will make you notice whenever there is time to stop for making an increase or a decrease, or something else you would like to be reminded of.
Second, the threads can help you to count rounds. Just put one end of the thread over to the other side of the work every time you reach the right number of rows.
Third, let the threads tell you which part of the work you have reached. One colour for the sides, one colour for midst back, and one for the beginning of the round.
Just find out what works best for you.
This bolero is an example of a knitting project where markers are needed at many points since it has fixed points for increases. For this knitting project you will need nine markers just for the body.
