confused on knitting needle and crochet hook

[TxCynDoll]

I have a pattern that calls for 3mm knitting needle (UK 11) this is a pattern by Pony out of England. The other is a 4mm (UK 8), my chart for knitting needles don't have a 3 mm, so would I use the 3 1/4 which would be a size 3...my chart has the 4mm which is my size 6, so I am hoping that this is correct... also crochet hook 2.5, but chart don't have 2.5, it has 2 1/4 which would be a B hook or 2 3/4 which is the C hook...confused because the 2.5 is in the middle, so it could go either way...

I know, u want to know what I am My mother has 6 poodles...yes u heard me anyway she don't knit, but she crochets, she wants me to teach her how to knit...well she has the pattern for a knit poodle and it's from the UK, but am confused on these sizes... also never heard of DK/snowflake chunky, what can I sub it with? I will be leaving in a few days by bus to visit my mother for a month...I want to make sure I have the right needles with me...

Thank u in advance for the help...

You need the needles/hooks that will give you the gauge needed for the pattern which may not be the same as the size used in the pattern as your tension could be looser or tighter. So work up some samples for your patterns with the closest sizes you have and see how many sts you get in 4" compared to the pattern gauge. Here's a needle/hook conversion chart, maybe that will help you sort it out.

On the yarn, I dunno. DK is a weight unless it's also a yarn brand and so is chunky. You'd probably need larger needles and hooks for the chunky weight yarn - what needle and gauge does it suggest?
