What if you have another ball that's a lace-weight solid color yarn that you don't yet have a project for?
What if you try to combine them? What size needle would you use? What would you make with them?
It's kind of a fun project to figure out.
For me, I decided to do a cowl. The chunky would be nice and warm and the lace-weight would allow me to add some nice details.
I started off with a sort of in-between needle size but quickly realized that it was going to be way too small for the chunky. Since I was going to be doing a lacy insert into plain stockinette, I realized I could use different size needles for each of the yarns with very little effort and bridge the gap that way.
So I did stockinette for the chunky using size 8-9 needles and then I transitioned to size 4 needles for the lace.
For the lace I did a really simple, super lacy old lace pattern called "faggoting" which is simply doing 1 round of yarnover/knit 2 together and 1 round of knit. These 2 rounds are repeated as often as needed to make it the length you want.
I did a few short sections in the bottom before knitting a long center section, basically to use up the whole skein.
I was going to do a long lace section before doing the edging but I got bored so it was shorter. This was one occasion I was glad of my sometimes short attention span because it came out much better.
I used a little 8-stitch VanDyke edging from the 1846 Cornelia Mee book to edge it (which took forever!) so it ended up like this.
So go explore your stash and try your hand at combining 2 different yarns that you might not have thought to put together. See what you come up with!
