View Full Version : Hook size confusion

07-24-2008, 06:18 PM
Just when I thought I had knitting needle size designations figured out, I get even more confused by crochet hooks!

I'm starting an afghan, from a sea-shell pattern (http://www.freevintagecrochet.com/afghans/sea-shell-afghan-pattern.html) I found. It says use worsted wool and "bone crochet hook No. 3 or 4". I found this chart (http://www.geocities.com/nornsneedlework/crochet/hookchart.htm), so I'm guessing it is the U.K. designation which means 6.5 or 6.0 mm. Does that sound right?

It looks reasonable to me. I'm not too concerned about the gauge, but I don't want it to be way off.

Thanks for any help!

What a confusing chart! As long as you use the mm size designated you can't go wrong.

The chart here http://www.purplekittyyarns.com/info/crochet-hook-conversion.html should be more helpful.

Thanks for the chart.

The pattern doesn't give a size in mm, all it says is "bone crochet hook No. 3 or 4". So would that most likely be a UK 3 or 4 (6.5 or 6.0 mm) or a US 3 or 4 (3.25 or 3.5 mm)?

I'm a total beginner, so I have no idea what would be typical for an afghan with worsted weight yarn.

If your doing an afghan then you want the 6-6.5 mm hooks. think of it this way a 6 mm knitting needle is a US 10 and 6mm crochet hook is J-US 10 also. Plus if you are using worsted weight yarn you want the 6 mm hook not the 3.5mm hook because it would be too small.

Thanks, that makes sense. I started with the 6 mm hook and it looks like it's working well.

According to the chart you found you are correct. In the US it would be a D or E size hook. I looked at the picture and the pattern and the size of the hook while though small is correct. The shells formed are small and not large. You could go up a hook size if you want the shells to be bigger. Otherwise hook with US , D or E, which is 3.25 mm or 3.5 mm.
>> I does look since it is an old pattern that back then the women didn't have the sizes in hook selection that we have now and while we would use a larger hook than they did then they made do with what they had.

Thanks mathwizard. I made a small swatch with a 3.5 mm hook, and the shells did come out smaller. But I like the result better with the 6 mm hook, so that's what I'll continue to use.
