Many knitters think "I am not yet good enough or experienced enough to knit with a good quality yarn" this a fallacy because it is much easier to work with a good quality. AND, if something goes wrong it can be unravelled and re-knitted even after washing and steam ironing as I myself experienced with design 75 in MAESTRO. Having made a mistake in the calculation for all the raglan shaping, after washing and steam ironing, I unravelled up to the beginning of the raglan and re-knitted it - not a trace of it on the finished garment!

Knowing how to cast-on, cast-off, putting on hold, increasing and decreasing is basically all that is required to knit most of the garments featured.
In addition, for some designs only, knowledge  of plating and transferring stitches from ribber to main bed correctly is required (transferring stitches on the single bed is basic knowledge of increasing and decreasing!). For that reason there are some step-by-step patterns available, as is for instance for design 75 - describing precisely (all supported with diagrams) how to work all the increases and decreases and more for ribber work.

Besides no fancy or complicated stitch patterns are required to compensate for the yarn quality - the simplest of patterns will look good.
