What makes this basket special
– A timeless rectangular shape that fits neatly on shelves, counters, nightstands, and desks.
– A diamond trellis motif that resembles a woven lattice, giving texture and visual interest.
– A sturdy construction that holds its shape with or without a lining.
– A pattern you can customize by color, size, and handle style.
– A free pattern that’s beginner-friendly but scalable for more advanced crocheters.
Materials you’ll need
– Yarn: Worsted-weight cotton or cotton-blend yarn works beautifully for a sturdy, smooth basket. You can also use a cotton/acrylic blend for extra quick-drying properties or a 100% wool blend for a cozier feel. Color ideas: a neutral base color (stone, ivory, or sand) with a contrasting color for the diamond trellis (deep blue, forest green, plum, or charcoal). You’ll use roughly:
– Base color: about 900–1,100 yards if you’re making a larger basket (about 12 inches long by 6 inches wide by 5 inches tall, before handles). If you’re keeping the size smaller or working with a lighter yarn, you’ll need proportionally less.
– Accent color: enough to create a few rows of diamond trellis in your chosen contrast if you’re doing color work; many crocheters prefer a simple single-color basket for a clean look, then add a two-color trellis for the lattice effect.
– Hook: A crochet hook in the range of 4.5 mm to 5.0 mm (US size: G/6 to H/8) is a good starting point for worsted weight yarn. If your yarn is tighter, move up a size; if your yarn is looser, go down a size.
– Notions:
– Yarn needle for weaving in ends and sewing in handles if you choose to add them.
– Scissors.
– Stitch markers (optional) to keep track of pattern repeats or to mark corners and increases.
– Optional finishing: a fabric liner (rectangular) to give extra stiffness, a pair of sturdy handles (cork, leather, or fabric-wrapped handles), or a cotton topping for a smoother, refined interior.
Gauge and sizing
– Gauge is important for achieving the intended size. In worsted-weight cotton, you’ll typically reach about 4 inches by 4 inches (10 cm by 10 cm) with around 14 stitches across and 9 to 10 rows in a basic stitch pattern.
– The Diamond Trellis motif helps create a sturdy, dense fabric, but you’ll want to test your gauge before starting. For this pattern, aim for about 14 stitches across and 10 rows tall per 4×4 inch swatch in the trellis motif.
– Finished size target (before handles and any lining):
– Length: approximately 12 inches (30 cm)
– Width: approximately 6 inches (15 cm)
– Height: approximately 5 inches (13 cm)
– If you want a larger or smaller basket, adjust the width of your base by adding or subtracting multiple of 2 stitches (to keep the diamond pattern aligned). For example, add 2 stitches to the base width to make it about 1 inch wider; add 4 stitches for about 2 inches wider. For height, add more rows to the base or to the sides to build up the walls.
Pattern notes and tips
– The trellis is created with a simple slip between stitches that forms diamonds across the surface. It’s essentially a filet-style lattice with solid stitches and deliberate holes to shape the diamonds. If you’re new to filet-style motifs in crochet, you’re in for a gentle introduction to the rhythm of a two-color or single-color lattice.
– If you choose to do a two-color trellis, you’ll be alternating colors across the same rows. To keep the pattern tidy, carry the unused color along the back of the work or cut and rejoin at the beginning of each row, depending on your preference for weaving in ends.
– Blocking helps the diamond lattice open up and shows the pattern clearly. If you block, use a gentle steam setting or a light spray and shape the basket to its final dimensions, then let it dry completely before use.
– Handles can be added in several ways:
– Integrated handles: Work long vertical channels on two opposite sides as you build the sides, then fold and seam the sides, leaving openings for handles.
– Separate handles: Crochet a strap or two handles separately and sew them on with a strong, matching thread.

Pattern: a complete, step-by-step guide
Overview
– Pattern is written for two identical front/back panels (Panel A) plus two shorter panels (Panel B) that become the sides. The panels are joined to form a rectangular box, with a flat base and optional handles. The main motif is the diamond trellis—created with a four-row repeat that forms diamonds across the surface.
Make Panel A (Front and Back)
– Aim for a panel size of roughly 12 inches tall by 6 to 7 inches wide, depending on your gauge. We’ll build a base of 12 inches by 6 inches using the motif, then extend upward in rows to reach about 5 inches of height.
Foundation row
– Ch 34. The chain length is designed to give you a width of about 6–7 inches (adjust by adding or subtracting stitches in multiples of 2 if you want a different width).
Row 1 (RS)
– DC in the 3rd ch from hook and in each ch across. You should end with 32 DC. Turn.
Row 2
– Ch 2 (counts as first DC). DC in the first DC, ch 1, skip the next DC, DC in the next DC, ch 1, skip the next DC, continue in this pattern to the end of the row. Turn. This creates the starting lattice space pattern.
Row 3
– Ch 2. DC in the first 2 DC, ch 1, DC in the next 2 DC, ch 1, continue this way across. Turn.
Row 4
– Ch 2. DC in the first 3 DC, ch 1, DC in the next 3 DC, ch 1, continue; the spacing begins to form a diagonal pattern that will align into diamonds as you repeat.
Row 5
– Ch 2. DC in all DC across. Turn.
Repeat Rows 2–5 until your panel is about 12 inches tall, or until you reach your desired height for the base plus the walls. If you want a taller basket, just continue the 4-row repeat.
Finish Panel A
– Transition to Rows that create the walls. You’ll want to add about 5 inches of height total for the walls (including the base). End with Row 5 to keep the pattern consistent across the surface.
Make Panel B (Sides)
– You’ll need two shorter panels to close off the box and form a rectangle.
Foundation row
– Chain 22. This gives you a base width of about 4–5 inches, depending on your gauge.
Row 1 (RS)
– DC in the 3rd ch from hook and in each ch across. End with 20 DC. Turn.
Row 2
– Ch 2. DC in first DC, ch 1, skip 1, DC in next DC, ch 1, skip 1, continue across. Turn.
Row 3
– Ch 2. DC in first 2 DC, ch 1, DC in next 2 DC, etc. Turn.
Row 4
– Ch 2. DC in the first 3 DC, ch 1, DC in the next 3 DC, etc. Turn.
Row 5
– Ch 2. DC in all DC across. Turn.
Repeat Rows 2–5 until you reach about 4 inches in height for Panel B, or adjust to your desired height. You’ll make two of these panels to be the two shorter sides of the box.
Joining the panels into a box
– Position the panels so that you have two longer panels (Panel A) for the front and back, and two shorter panels (Panel B) for the sides.
– Seam the rectangles together along the edges using a mattress stitch or slip stitch seam with a yarn needle. Start by aligning the long edge of a Panel A to the long edge of a Panel B and seam with a repeating running stitch or a shallow slip stitch seam. Do this along all four corners so that you end up with a rectangular tube.
– For a firmer box, you can add a base. Crochet a flat rectangle in the same diamond trellis pattern, sized to fit the bottom inside of your box, and sew it to the bottom seam.
Optional lining and handles
– Lining: If you’d like a more polished finish, cut a liner to fit inside the box and sew it to the seam lines with a zigzag or backstitch. You can use a fusible fabric adhesive for extra stability, then stitch around the edges to prevent fraying.
– Handles: Add handles by either:
– Integrating handles during the building stage: Crochet a small panel or two vertical channels on opposite sides of Panel A and weave in the ends to form a handle openings.
– Attaching handles afterward: Crochet two handles in your preferred color and material (fabric-wrapped, cork, leather, or sturdy yarn) and sew them to the inside top edge near the corners. Use a secure backstitch or ladder stitch to ensure they hold up to weight.
Color variations and design ideas
– Two-color diamond trellis: Use the base color for the panels and a contrasting color for the lace-like diamond accents. Change color every 4 rows to create a bold lattice across the entire surface.
– Single-color option: A single color creates a clean, modern look while preserving the texture and depth of the diamond motif.
– Multi-diamond option: If you’re feeling ambitious, design several diamonds in a gradient of colors along the length of the basket for a rainbow or sunset effect.
Care instructions
– Washing: Hand wash or gentle machine wash on a cold cycle with a mild detergent.
– Drying: Do not wring; lay flat on a towel and reshape as it dries.
– Blocking: Light blocking helps the diamonds pop and keeps the rectangle square.
Common questions you might have
– Can I make this basket larger? Yes. Increase the width of the base by adding stitches in multiples of 2. You can also add rows to the panels to achieve more height.
– Can I use thicker yarn? You can, but you’ll need to rework the gauge and adjust hook size accordingly. A thicker yarn will produce a warmer, sturdier basket with a heftier feel.
– What about a lining? A fabric liner will give your basket a refined finish and prevent small items from poking through the lattice holes if the basket is used to store loose items. It’s a simple, effective upgrade.
– Are there alternative stitches I can use? Absolutely. If you’re more comfortable with moss stitch or a basic filet motif, you can substitute your preferred lattice-style stitch to achieve a similar diamond effect.
Step-by-step pattern recap (quick reference)
– Make two Panel A panels: approximately 12 inches tall by 6–7 inches wide, using Rows 1–5, then continue Rows 2–5 in a 4-row repeat to build the height.
– Make two Panel B panels: approximately 4 inches tall by 4–5 inches wide, using the same motif with a narrower base width.
– Join panels along the edges to form a rectangular box.
– Add a base panel if desired for a fully enclosed bottom.
– Optional: add a liner and handles for a finished look.
A few additional tips for success
– Tension matters. If your gauge is too tight, the box may be stiff to seam; if too loose, it won’t hold its shape. Adjust accordingly by changing hook size or yarn weight.
– Keep your edges neat. When joining panels, try slip-stitch seam or a mattress stitch to produce tidy, nearly invisible seams.
– Test a small sample. A compact swatch with the trellis motif will help you confirm gauge and understand the pattern rhythm before you commit to the full basket.
Inspiration and usage ideas
– Organizing space: Use this basket on a desk or shelf for office supplies, notepads, or mail. A larger version can hold craft supplies, knitting notions, or small sewing kits.
– Plant holder: Place a rigid pot or planter inside the basket for a decorative, protective cover that complements your decor.
– Gift basket: Fill with handmade soaps, candles, or a small plant, and tie with a ribbon for a thoughtful, homemade present.
– Home decor: The diamond lattice texture adds a tactile element to your living room, entryway, or bathroom; display it on a shelf with other woven or crochet pieces.
