Too small crochet hook for this pattern?

Hi, first i say it's probably best to just spend the $2 bucks on the hook that's called for (especially for a beginner). Honestly if you enjoy crocheting than I'd say get ALL the hooks so you can easily adjust a project without having to run to the store when your feeling inspired... Either way you need to do a test swatch, there is usually a reference to it in the beginning of the pattern, such as 3 st = 1inch or something like that. So when you do your swatch with any hook and/or yarn you should have 3 stitches =1 inch. Cast on about 25 sts and make about 15 rows, then you get a ruler and without pulling flatten the swatch and see how many sts = 1 inch.So if you're getting only 2 sts =1 inch, you can use a thinner yarn or smaller hook. 4 sts =1 inch a thicker yarn or larger hook. I know its confusing in the beginning but keep at it you'll get the hang of it! I hope this helps. Also a great reference book that is well written and even has a sense of humor as well as awesome patterns is The Happy Hooker by Debbie Stoller. I'm mainly a knitter but this book inspired me to try crochet. Good Luck! Keep on stitchin'! **Also I am starting a web site cult9design.com , selling all original art to wear and share.
