pulling wools over my own eyes

Cotton, linen, acrylic, alpaca, wool...100%, 70%, 30%.....3 ply, 4 ply, 8 ply.

That is not all, for crochet, there a choice between yarn and thread. For thread, you have size 3, 10, 20 and 30. When you have finally decided on the yarn, you have to find the correct hook size. Sigh....cross stitch is so much more straightforward.

If any kind soul can direct me to info on crocheting ie. not how to crochet but how to decide what material to use, please leave a comment. Thankssss!
