The first step to assemble a blanket of knitted blocks is to decide the distribution of the pieces and block them. Some people prefer to block them first and then think about their distribution, and others choose to first decide the distribution and then block. I usually choose the second one because it allows me to block the squares in batches. This way, while the second batch of squares in the process of blocking is drying up, I start sewing the first batch 🙂 If you don’t know how to block your squares or want to see a step-by-step guide, I suggest you take a look at my article on blocking.
To give you an example of the whole process I share the photos of the assembly of my “12 blocks for Xmas” blanket (click for the free pattern).
Play with them, placing them in different places until the layout is just as you want it to:
There are several ways to join the blocks, and I show below the ones that I use the most. Before choosing the method however, it is necessary to decide the direction of the joins that will be made first. I recommend that you always make the horizontal ones between blocks, for example, and then all the vertical joins. That’s what I usually do.
I use this seam to join one bound-off edge with one casted-on one (or two bound-off or two casted-on edges). You need to have the same amount of stitches in each piece because it is worked stitch by stitch, recreating a row. Here’s how to do it:
This seam uses single crochet stitch to join the pieces together. If you want to add some nice texture on the right side of your work, you can hold your squares with the wrong sides together when joining. This way, the single crochet seam will be visible on the right side. However, I give you below the instructions to join the squares leaving the seam in the wrong side.
Once you finished joining your blocks with horizontal seams you’ll end up with strips of squares:
Now it’s time to join these strips. For an invisible seam you can use either mattress stitch (if you’re joining together pieces in stocking stitch) or, like I show you below, use edge-to-edge seam to join pieces with garter stitches at the sides.
This is a flat seam (no bulky join at the wrong side!) that uses the side knots left by the garter stitches at both edges:
I hope you find all the info useful!
