If you just want to start with a plain block quilt here is the instructions.
1. decide what size blocks you want to use.
2. cut blocks the finished size plus 1/2 inch.
3. start sewing blocks in a row until the quilt is the width you want.
4. from this row decide how long you want you first quilt to be.
5. multiply the number of blocks across by the number of block down and then subtract the number of blocks you already have cut.
6. cut the remaining blocks out.
7. sew the blocks into rows like the first one you did.
8. press the seams to the left on even rows and to the right on odd rows.
9. sew the rows together in 2s ie 1+2 3+4 5+6. pin the seams so they line up and don't move.
10. keep sewing and pressing rows until you have one finished top.
Important points: Make sure all blocks are cut the exact same size. Make sure all seams are the same width. Most quilter's use 1/4 inch seams but I have seen larger. It is only important that all seams are equal so blocks line up when sewing into rows.
I hope these simply instructions help you be less frustrated.
