Garment Overview

The Bumpy T-Shirt is a seamless, top-down or in-the-round construction knitted garment designed to be worn as a casual everyday top. It features a structured body with defined side seams marked by stitch markers, set-in or raglan-style sleeve shaping, and a distinctive multi-colour textured pattern across the entire fabric. The finished garment has a relaxed chest measurement suited to a range of adult sizes.

Sizes and Finished Measurements

• Sizes available: S, M, and L
• Chest circumference: 96 cm (S), 105 cm (M), 112 cm (L)
• Length: 66 cm (S), 67 cm (M), 68 cm (L)

The generous chest measurements suggest a comfortable, slightly oversized or relaxed fit, making the Bumpy T-Shirt a versatile wardrobe piece suitable for a variety of body types.

Yarn: BC Garn Allino

The pattern calls for BC Garn Allino, a DK weight yarn that is the signature material for this design. Allino is a yarn known for its natural fibre composition and pleasant drape, making it well-suited to garments worn close to the body. Three distinct colours are used throughout the pattern, contributing to the visual interest of the bumpy texture:

• Colour I (cl35): 4 (5) 5 balls
• Colour II (cl34): 4 (5) 5 balls
• Colour III (cl33): 3 (3) 3 balls

The use of three coordinating shades of BC Garn Allino gives the finished top its characteristic multi-tonal, textured appearance. Knitters should ensure they purchase the correct colour codes — cl35, cl34, and cl33 — as specified in the pattern to achieve the intended colourway.

Needles Required

• 3.0 mm circular needles (UK size 11 / US size 2½) — used for ribbing or cast-on edges
• 3.5 mm circular needles (UK size 10 / US size 4) — used for the main body and sleeves in pattern

Both needle sizes are required in circular form, as the garment is constructed in the round. Knitters working with magic loop or double-pointed needles may adapt accordingly, particularly for the sleeve sections where stitch counts are smaller.

Tension / Gauge

Achieving the correct tension is essential for this pattern. The stated gauge is:

• 26 stitches × 36 rows in pattern on the larger (3.5 mm) needle = 10 × 10 cm

Because the bumpy stitch pattern is used to measure tension rather than plain stockinette, knitters are strongly encouraged to work a full tension swatch in pattern before beginning the garment. Even a small deviation in gauge can significantly affect the finished chest width and length across the three sizes.

Construction Method

The Bumpy T-Shirt is worked in the round on circular needles, beginning with a cast-on of 248 (272) 296 stitches on the smaller 3.0 mm needle. Four stitch markers are placed at the
