Specifically I want to learn how to knit a hat.like a beanie of sortsAlso where can I get supplies to do said knitting?
If you sew or glue it to the stretchy knitting or crochet a lot (and especially around the outside edges), and the self-adhesive type isn't best for sewing through)Otherwise the velcro will be too wobbly or pull on the knitting/crochet too muchNote that Velcro comes in different strengths, shapes, colors, and in sew-on or self-adhesive versions.
Use the soft sew on velcroSew on by hand.
Books and YouTube are a good place to start, but I found a really wonderful source for helpLook online to see if there is a fiber arts guild in your area (you may be surprised- they are more common than you would think!)Usually there are several knitters available who would love to share their craft with you and will patiently put up with you while you mess up and can't remember for the 4th time how to cast on or whateverI learned this way, and it was really helpfulNot only that, but these folks meet regularly and often provide great refreshments (the ones I met were fabulous cooks!) and discussion at meetings, as well as being willing to teach you other crafting skillsAnother neat tool is the Knifty Knitter looms sold for children to learn onThey are simple to use and will make hats from infant size to XL, depending on which loom size you useThey can be found at craft and fabric shopsI use doubled up yarn on the larger sizes for a thicker, warmer hatI teach my school students this way, and was most proud of a 7th grade boy who did a grunge-type beanie in double black and white thread that he sewed a skull patch ontoHe was thrilled with himself!
