Case for 15 inch laptop

Case for 15-inch Laptop by Minttu

Project Overview

This advanced knitting pattern creates a protective case designed to fit a 15-inch laptop. The finished case measures approximately 39 cm x 26 cm when sewn, providing secure storage and portability for your device. The design combines functional construction with colorwork knitting techniques, making it both practical and visually appealing.

What Is Being Made

A knitted laptop case featuring a colorwork design in grey, yellow, and white. The case includes a cotton fabric lining and a 70 cm zipper for secure closure. The knitted piece is folded and sewn to create a protective sleeve that accommodates 15-inch laptops.

Knitting Techniques Used

This project employs stranded colorwork knitting, a technique where multiple yarn colors are carried across the back of the work to create patterned designs on the front. The colorwork follows a provided chart, requiring the knitter to work with multiple colors simultaneously while maintaining consistent tension and stitch quality. This advanced technique demands careful attention to yarn management and pattern reading.

Stitches and Stitch Patterns

• Stockinette stitch: The primary stitch used throughout, created by knitting all stitches on right-side rows and purling all stitches on wrong-side rows
• Colorwork pattern: Worked from a chart using the stockinette stitch base with color changes to create the design
• Gauge: 19 stitches and 22 rows per 10 cm (4 inches) over stockinette stitch on size 4 mm needles

Materials and Specifications

Yarn: Paksu Pirkka-lanka worsted weight yarn (tex 285 x 2). Total yardage required: grey 45 g, yellow 40 g, and white 30 g. The worsted weight provides structure and durability suitable for a protective case.

Needles: Size 4 mm (US 6) needles for knitting the main piece.

Additional Supplies: A 70 cm zipper for closure, cotton fabric for lining (41 cm x 55 cm), and sewing materials for assembly.

Pattern Construction

The knitted piece measures approximately 41 cm x 55 cm before finishing. You will cast on 75 stitches using grey yarn and work following the colorwork chart until the piece reaches 55 cm in length or your desired measurement. The pattern is then cast off. The finished knitted rectangle is folded in half with right sides facing, seamed along the sides, and lined with cotton fabric before the zipper is installed.

Finishing and Care

After knitting is complete, the piece is gently wet-blocked by hand and laid flat to dry, which helps set the stitches and even out the fabric. The work is then gently steamed through muslin to further refine the finish. This careful finishing process ensures a professional appearance and proper shape for the case.

Difficulty Level

This project is classified as advanced, suitable for experienced knitters comfortable with colorwork techniques, chart reading, and garment construction including seaming and lining installation.
