there are LOTS of ways to increase… (and make 1 is a generic increase)
some increases (like YO’s) are very visible
some increases (like a lifted or raised increase) are much less conspicous.
you can use the easiest one for you, (or use the pattern as a learning experience and learn a new Make 1, and practice it, again and again.
the most important thing is: PICK a STYLE and stick with it --for the entire pattern!
make the pattern again and PICK A DIFFERENT STYLE–and see what a difference a different choice of MAKE 1 can make!
any good knitting reference book will illustrate 3 or 4 (there are about 6 to 8!) ways to increase.
You might find there is one particular style you like more than others… you can always use it, (and use your style instead of the suggested one in a pattern)
