MMMbop!

June 22 MOA meetup

Barb wrote an article about hook sizes below.  She'll also be teaching our class this weekend.  Details including the pattern were sent out with the newsletter, or you can check our Crochet Twin Cities: Meeting Calendar, or our social media. Limited printouts of the pattern will be available at the meeting.

The other side of the table.

It can be difficult to realize, but those three blond brothers had their huge one-hit-wonder back in 1997. It has been a long time. It’s around that time that I decided I needed to ditch the alphabet soup of hook sizes and do like the Hanson Brothers. MMMbop!


The brothers sang about a secret that no one knows. It took me decades of crocheting to figure out that the alphabet sizing of crochet hooks, just like women’s clothing sizes, had no uniform standard. A G could be 4 mm or 4.25 mm or any other size the manufacturer chose to stick on the thumb rest. Further complicating matters is that the hook sizes for thread crochet have another completely different sizing system. The UK also has an older, non-sequential numbering system. And Japan has yet a different system. These days I stick to standard millimeter sizes. A 4 mm will always be a 4 mm. 


Here is a rough equivalent chart. I cross referenced 15 different charts, as you can see there is little agreement on anything, but MM. Because hook manufacturers and hook size chart makers have no true sizing standard, other than mm. Join me hooking to the MMMbop!
