After you've gotten your pieces cut the next step is to put them together. When you piece a quilt top the first thing you have to know is that the pieces that go together all have to be the same size, and they usually start with the smallest pieces you've cut. You can see here I've got two squares. They fit together. You would seam them, sew them down, right here. That would give you this part of the block. You're going to sew these two together, and that would give you the top half. When both of these are sewn you're going to sew this completed piece to this completed piece, and you're going to end up with a block that looks like that.
Now, to make the top you would put one block right next to the adjoining block, sew those together, and you've got the beginning of your row. So, blocks are your basic components, and blocks get combined into rows. Once you've done that you'd do your second row. You'd sew your second row together. Then you'd sew row one to row two. And it just keeps building like that. It's very logical.
Once you've made your blocks there are lots of different ways to put them together, and that's part of the fun of quilting. You can arrange them over and over until you find a pleasing combination. They don't have to go across. Another way they can be sewn together is on the diagonal. So, you can put your blocks like this. They're still sewn in rows. Rows are the basic elements, but they're sewn in rows of 45 degree angles. And they just build. You put your next row here. Sew that to this row.
These are just a few of the ways you can put a quilt top together. You can have lots of fun experimenting and you'll come up with lots more.
