Just something about yarns

Dear readers, some net forums make us knitters wonder, what is luxury yarn and what is ordinary yarn. Pure wool (if I buy it from a store) and wool blend are "ordinary" yarns in my eyes. In this context wool blend means something like 75 % wool, 25 % polyamide. That kind of yarn is OK for...let's say mittens and scarves and sweaters.
If the yarn has acrylic in it, the yarn is definitely ordinary yarn. I don't use such yarn to knit anything for myself. My skin becomes very itchy and bleeds, if I wear something made of acrylic. Or if I don't become itchy, it makes me feel very hot. So acrylic yarn is very, very ordinary yarn in my world.
There are times when 100 % wool yarn is ordinary yarn. But if I have made the said 100 % wool yarn myself from roven, that is luxury yarn for me, because the roven has gone through my wheel and I've taken care of spinning myself. That kind of yarn needs special home and special owner, who is knitworthy, as they say.
When the yarn I have bought from a store has silk in it, that yarn is luxury yarn. That means I may have difficulties to decide the future of such a yarn. The same is true if I get yarn someone has hand - dyed. I may wait for the right time and the right person to dare to knit such yarn.
If the yarn has been made in Peru and has merino wool in it, it is definitely luxury yarn in my eyes. I may use it to knit some squares for a blanket of some little prince or princess. Not actual prince or princess, of course. The actual princes and princesses' parents, like in Great Britain, would not accept gifts from someone like me they've never met.
Let's knit, shall we?
