I am new to crocheting and am trying to teach myself. I have a book of patterns for certain stitches and came across something I didn't understand. After the instructions it went like this- : 5 ch-2 sps. Can someone tell me what this means? I thought it was chain 5 but that would have read ch 5 not 5ch. Please tell me without the abrevs. I'm just not getting it. Thanx.
