Buying doubles is good but sometimes you have your own stash you bought a while back and have been wanting to use but you only got pne skein or cake, this is where this tutorial I found comes into play.
At first glance I thought it was so complicated and it made me fear getting my yarn tangled up casuing a bigger headache. But after trying it out it actually really works!
The downside is, it has to be done in 3 strands when there are times I only want it in 2. But this is still very useful.
So here it goes....I also made a video of this to make it clearer
First this is make an s shape with your yarn
Pick up the 3 strands
Make a slip knot
Then chain away
When you run put of the 3 strands, pick up your working yarn (meaning the yarn that's attach to the skein) between the loop and pull to make a longer 3 strand yarn
There you go lace to medium weight ❤️
I hope I was able to describe it well eith eords and photos but if you can't get it, here's the video I made ❤️
