How to join / sew granny squares together I

 This is a good solution for joining grannies with an almost seamless effect, specially for dresses and sweaters.

Lay the motifs out in the correct order with the right sides up. Working in horizontal rows, stitch the motifs together, beginning with the top row of motifs. 

Begin stitching at the righthand edge of the first two motifs, sewing into the back loop of corresponding stitches.

Continue stitching the first two motifs together, making sure you join only the back loops of each edge together, until you reach the lefthand corner. Align the next two motifs, carry the yarn firmly across and join them together in the same way.

For extra strength, you can work two stitches into the corner loops before and after carrying the yarn across.

Continue joining motifs along row, then secure the yarn ends carefully at the beginning and end of the stitching. Repeat until all the horizontal edges of the motifs are joined.

Turn the crochet so the unstitched edges of the motifs are now horizontal. Working in the same way as above, join the remaining edges together with horizontal rows of stitching.

When working the corners, tabe the needle under the stitch made on the previous row.
