I have not read all the other responses so that my answer will be totally my own first impression!
I love the yarn, and if I was teaching a beginner knitting class for a garter stitch scarf, I’d say GO FOR IT to anyone asking!
And another thing…I think a pretty yarn breaks the monotony! I love your choice of yarn! Makes me wish I’d found this yarn on Ebay instead of you! :teehee:
The sparkly part of the yarn looks like it’s pretty much embedded into the colored yarn…and won’t be too much trouble for you, like splitting or anything. I’ve always like this type of yarn, the way it’s constructed.
And WOW! 187 yards each ball! That will make a perfect scarf! If you buy this yarn in particular, I’d use bamboo needles, and at least a US9 or US10. Don’t crowd the stitches.
Cast on about 20 stitches only. And away you go! If you like extra wide scarves, cast on 25 stitches.
