Just thought I'd pass along an option for knitting squares to meet the 8" x 8" requirement for the Jason Blanket. This square is knit in the round until it measures 8 inches square - no swatch necessary. It's the pattern I've used for a three of the most recent baby blankets I've done. The pic is just an example from a square used in a previous blanket.
With double-pointed needles, cast on 4 stitches.
Round 1: Increase 1 in each of the 4 stitches. You'll have 8 stitches.
Distribute the stitches onto four needes, two stitches per needle, and begin knitting in the round.
Round 2: Knit one, increase one with each stitch. You will now have 4 stitches on each needle (16 stitches total).
Round 3: Knit one, increase one, knit to the last stitch, increase one. You will have 6 stitches on each needle.
Round 4: Knit even the entire round.
Round 5 through 7: Knit one, increase one, knit to the last stitch, increase one.
Round 8: Knit even the entire round.
Continue the same pattern, increasing in the first and last stitches on each needle the first three of every four rows until you have a square that's 8" x 8".
Switch to circular needle if necessary. Bind off purlwise.
