KGeometry: Square Venn Diagram

Square Venn Diagram Coaster or Pot Holder by knitvana

Project Overview

The Square Venn Diagram is a knitted coaster or pot holder design from the kGeometry collection by knitvana, featuring geometric patterning inspired by mathematical Venn diagram concepts. This finished piece measures 8.5" x 8.5", making it a practical yet decorative table setting accessory suitable for protecting surfaces from hot dishes or beverages.

What Is Being Made

This pattern produces a dual-purpose knitted square that functions as either a coaster for drinks or a pot holder for hot cookware. The design incorporates geometric visual elements through knitted colorwork or stitch patterns that create a Venn diagram aesthetic. The finished piece includes an optional hanger attachment with a button detail, allowing it to be displayed or stored conveniently in a kitchen setting.

Techniques Used

The Square Venn Diagram employs fundamental knitting techniques combined with charted pattern work. The front side is constructed by following diagram instructions, which typically indicate stitch placement for creating the geometric design. The back side uses a classic stockinette stitch base created through alternating knit and purl rows. An optional hanger component is worked separately using ribbed knit and purl stitching, with a button loop incorporated by dividing stitches partway through the knitting process.

Stitches Used

• Knit stitch (K) – the fundamental stitch used throughout the piece
• Purl stitch (P) – used on even rows of the back side to create stockinette texture, and in the hanger's ribbed pattern
• Charted stitch patterns – for the front side geometric Venn diagram design
• Cast on and cast off – edge techniques for securing stitches at the beginning and end

Materials and Tools

This pattern requires size #3 knitting needles for constructing the main piece. The PDF specifies casting on 40 stitches for the back side, with 53 total rows worked in the stockinette stitch pattern. Yarn weight and fiber content are not specified in the pattern documentation, though the needle size suggests a lightweight to sport-weight yarn would be appropriate. The hanger component begins with 8 stitches and continues to the desired length before being cast off.

Pattern Structure

The coaster or pot holder is worked as a two-sided square. Odd rows 1 through 53 are worked entirely in knit stitch, while even rows 2 through 52 are worked entirely in purl stitch, creating a smooth stockinette finish on the back. The front side features charted geometric patterning that creates the Venn diagram visual. The optional hanger is a separate component worked in alternating knit and purl ribbing, with stitches divided after 4 rows to create a button loop, then continued to the desired length.
