You may have seen them on Pinterest or Facebook: Ultra-chunky throws and blankets made with super-bulky yarns. And then you realise that it can be difficult and often expensive to get hold of super-bulky yarns.
What about making your own? It is easier than you think!
Crochet method: Take a bulky yarn you like. Anything in 12-14+ ply that will work with needle size 6-8mm upwards will be fine for this. Use either your fingers or a big crochet hook and crochet a chain. This will be your extra bulky yarn! You can make it even thicker by working with two strands of yarn. Keep going until you have created a chain long enough to work with.
Use the Frankfurt Knot to add a new strand of yarn. The Frankfurt Knot is a clever knot that is very strong and at the same time very small. No need to weave in the ends - you can cut the yarn very close to the knot and it won't come undone.
The following video shows how to do this knot. (This video is not in English, but you can turn the sound off - the demonstration is pretty self evident).
Spool knitting method: Use a yarn you like, it doesn't have to be super-bulky. Make a long cord on a spool knitter (also know as Knitting Nancy or French Knitter) and use that as your yarn.
To spool knit with thicker yarn, make your own spool knitter using a toilet paper roll and four paddle pop sticks. You can use this the same way as a Knitting Jenny.
