Hartland Slipper Socks in Berroco Ultra Wool – Pattern Summary

The Hartland Slipper Socks is a knitting pattern designed by Amy Christoffers and published as part of Berroco Portfolio Vol. 4. Available as a downloadable PDF, this intermediate-level pattern produces a pair of cozy, colorblock slipper socks worked in Berroco Ultra Wool at an aran weight. The finished socks measure 9 inches long (heel to toe along the bottom of the foot) and 8 inches around the foot, sized as a single universal fit.

What Is Being Made

This pattern creates a pair of slipper socks — thick, cushioned knitted socks designed to be worn as house slippers. The two-color design uses a contrasting color for the toe section and a main color for the body of the sock, giving the finished piece a clean, graphic look. Because both socks are worked identically, the pattern instructs knitters to make 2, ensuring a matching pair.

Construction Method

The socks are constructed toe-up, meaning knitting begins at the tip of the toe and progresses toward the cuff. This approach allows knitters to try on the sock as they go and adjust the foot length before committing to the heel and leg. The toe is shaped using a Turkish Cast-On, a provisional cast-on technique that creates live stitches on two sides simultaneously — ideal for seamless toe-up construction. Stitches are then increased on every other round to shape the rounded toe.

The pattern is written for two circular needles (two 16-inch circulars used simultaneously), but Amy Christoffers notes that knitters may substitute the magic loop method or double-pointed needles (DPNs) according to personal preference. Stitch markers are recommended when using alternative methods to track needle divisions at the toe and heel.

The heel is worked using waste yarn to hold heel stitches, a technique associated with an afterthought or peasant heel construction. This method involves knitting across the heel stitches with scrap yarn, continuing the sock, and then returning later to remove the waste yarn and pick up the live stitches to work the heel separately. This results in a tidy, reinforced heel pocket.

Techniques Used

• Turkish Cast-On – a two-sided provisional cast-on for seamless toe-up starts
• Toe-up construction – working from toe toward the cuff
• M1R (Make 1 Right) and M1L (Make 1 Left) – directional increases used to shape the toe
• Waste yarn heel – holding heel stitches on scrap yarn for afterthought-style heel construction
• Working in the round – using two circular needles, magic loop, or DPNs
• Sewn Bind-Off – a stretchy finishing technique worked with a tapestry needle threaded with the yarn tail
• Two-color knitting – contrasting color (CC) used for the toe, main color (MC) for the body

Stitches Used

• Stockinette Stitch (St st) – the primary stitch pattern worked in the round, creating a smooth knit fabric on the right side
• Increase stitches – M1R and M1L worked at the edges of each needle to shape the toe

Yarn and Materials

The pattern calls for Berroco Ultra Wool, an aran-weight yarn sold in 100-gram balls. Knitters will need one ball each of two colorways:

• #33147 Stonewashed – used as the Main Color (MC) for the body of the sock
• #33117 Kohlrabi – used as the Contrasting Color (CC) for the toe

Berroco Ultra Wool is a superwash-treated wool yarn known for its stitch definition, durability, and ease of care — qualities that make it particularly well suited to sli
