There are no visible "shells", an no "seashore". I'm questioning the name choice of this pattern. Especially since I already have one with the same name. https// == ochet-pattern-seashells-by.html

Looking at the diagram really helped me to understand the design. I consider myself a visual learner and the diagram really made it real to me. This is sort of like a ripple pattern but on steroids. By using more than one color this is really what makes it really stand out. This pattern is going to the top of the stack.

There is something oddly attractive about this design. The stripe pattern is really pretty but there is something about the color selection. The white section throws it off some how but it still seems to work. I would probably select different colors to make this seashells by seashore afghan because I love the pattern.

This Seashells by the Seashore afghan is stunning! I love the design the 5 row repeat makes. The idea of changing colors every 5 rows really make the pattern stand out. The written pattern right here on this page is well written and easy to understand and follow. I'm so looking forward to making this one. 20 balls of the Bernat Handicrafter Cotton yarn will make a good size afghan/blanket. I haven't seen this yarn yet, so I will keep my eye out for it and pray it doesn't cost a lot. Thank you for sharing this free crochet blanket pattern.

Wow! What a fantastic color scheme and the stitches used, I need to look at the pattern first. But for this color combo, I think this would look beautiful in a scarf using a different kind if stitch. Well, the possibilities are endless. Thanks for the pattern. Appreciated. Cheers!

Love this pattern. Making it for my son. Thank you so much for this pattern.
