The My First Baby Blanket free knitting pattern in Plymouth Encore Worsted Colorspun is a 1-page PDF on US Letter paper, originally published in 2000. It is a simple garter-stitch blanket with a seed-stitch border, worked in a double strand of Plymouth Encore Worsted Colorspun yarn.
What the pattern includes
The pattern lists 4 - 100g balls of Encore Worsted Colorspun, shown in color 7711, and a 24" circular needle in size US 13. The gauge is 2.5 stitches per inch over the pattern, and the finished blanket measures 28" x 32". You cast on 73 stitches loosely.
Knitting and finishing the blanket
Work the border rows, then repeat Rows 11 and 12 — knit across, then knit 7, purl to the last 7 stitches, and knit 7 — until the piece measures about 30 inches. Bind off loosely in knit stitch. The pattern is free with yarn purchase; print at actual size on US Letter paper.
Yarn note
Plymouth Encore Worsted Colorspun is a worsted-weight yarn, and the pattern calls for holding it double throughout.
