Aargh! I think I'm now on my 4th attempt at doing a wave afghan pattern and all say different things! I have done YouTube searches for these stitches and every video says different! Basically, when doing a wave pattern, how do I tr2tog and tr3tog?? Could you explain where I am going wrong because when I turn and try and match the waves on the other side, it's not playing ball so my waves are not matching up!! Thank you in advance if this makes sense!
