Look,
I sew, knit, crochet, macrame and kumihimo. I understand those things.
Still, I look at Quilts and Spun yarn, and freehand Embroidery, and Amigurumi - and my brain screams 'WHAT MAGIC IS THIS!?'
What yarn / thread-craft makes your brain go 'boing' despite knowing how the fundamentals work ?
[Yes I know Amigurumi is knitting / crotchet but it's also structural sculpting which is different to flat piece or loom knitting]
