I am crocheting a blanket made with granny squares and trying to find a way of attaching them without ridges. The single crochet attachment technique leaves ridges and I would like a smooth transition from one square to the other for both sides of the blanket. Does anyone know a way to do this, or if there even is one??? Any help would be appreciated!
In your Search Engine, be it Google, Bing or another, put in the words: attaching granny squares together".
There are videos, pictures and written instructions sites on how to put your granny squares together.
All you have to do is try a couple of the ideas and find out which one you prefer.
I think you will find just what you are looking for in a couple of these sites.
This one makes a zig zag look....but it is raised slightly...put both squares together, right sides facing you. Join yarn with a slip stitch through the bottom corner stitch on one square. Keeping the yarn underneath, put your hook into the bottom corner stitch of the other square and pull a loop up and through the loop on your hook (slip st). Slip stitch in the 2nd st of the 1st square and then back to the 2nd st of the 2nd square...continue alternating slip stitches in this manner till you get to the end. Fasten off. It was in a pattern I had for joining mile-a-minute pattern strips.
To see how it looks, it's the pink & white afghan featured on this link: http://www.leisurearts.com/products/mile-a-minute-peek-a-boo-ripple-baby-afghan-crochet-patterns-digital-download.html
