Berroco Lighted Structures Venturi Top Crochet Pattern

Berroco Lighted Structures Venturi Crochet Top

What Is Being Made

The Venturi is a crocheted top designed by Alison Green, offered in multiple sizes ranging from 37½" to 69½" bust circumference. This intermediate-level garment features a finished length of approximately 23 inches and is designed with positive ease of 4–6 inches for comfortable wear. The pattern includes four base sizes with additional bracketed and braced options to accommodate a wide range of body measurements.

Construction Method

The Venturi top is constructed by working the front and back pieces separately from the bottom up, then seaming them together. This modular approach allows for precise shaping and easier gauge management during the crochet process.

Crochet Stitches and Techniques

The pattern employs several specialized crochet stitches to create its distinctive structure:

• Single crochet (sc) — used for foundation and stitch placement
• Treble crochet (tr) — a tall stitch that provides vertical dimension
• Chain stitches (ch) — including ch-2 and ch-5 spaces that create openwork elements
• Trdctr3tog (triple double triple crochet 3 together) — a specialized decrease stitch created by working yarn over twice, inserting the hook in the indicated stitch, pulling up a loop, pulling through 2 loops twice, then inserting the hook in the next stitch and repeating this process. This complex stitch reduces three stitches into one, creating texture and shaping.

The pattern stitch is built on repeating units that combine these stitches with chain spaces to form an open, structured fabric. Gauge is measured after blocking and is established at 5 pattern repeats (equivalent to 20 stitches) and 8 rows equaling 4 inches in the pattern stitch.

Materials

Yarn: Berroco Modern Cotton DK in colorway #6668 Rosecliff. Yardage requirements range from 3 hanks (100 grams each) for smaller sizes up to 4 hanks for the largest sizes.

Tools: A size E (3.5 mm) crochet hook or the size needed to obtain the specified gauge, plus removable stitch markers to track pattern repeats and shaping.

Skill Level

This pattern is rated as intermediate difficulty, requiring familiarity with basic crochet stitches, the ability to work complex decreases like the trdctr3tog, and comfort reading multi-sized patterns with bracketed and braced sizing options.
