Whether you're a seasoned knitter looking for a quick weekend project or a beginner eager to learn new techniques like yarn overs and decreases, this pattern is designed to be accessible and rewarding. Let's dive into creating these charming, textured coasters that are as functional as they are beautiful.

Materials Needed

Before you begin, gather the following materials to ensure a smooth and enjoyable knitting experience. The quality of your yarn and tools will directly impact the final look and durability of your coasters.

Yarn

• Main Color (MC): Worsted weight cotton or cotton-blend yarn in Sage Green. Cotton is ideal for coasters as it is absorbent, durable, and holds its shape well. You will need approximately 50-60 yards per coaster.
• Contrast Color (CC): Worsted weight cotton or cotton-blend yarn in Cream White for the crochet border. You will need approximately 10-15 yards per coaster.

Needles & Notions

• Knitting Needles: US Size 6 (4.0 mm) knitting needles, or the size needed to obtain the correct gauge. Straight needles are perfect for this flat-knit project.
• Crochet Hook: A US Size G/6 (4.0 mm) crochet hook for the single crochet border.
• Tapestry Needle: For weaving in ends and finishing.
• Stitch Markers: 2 stitch markers to delineate the border from the chart pattern.
• Scissors: For cutting yarn.

Gauge

20 stitches and 28 rows = 4 inches in stockinette stitch. Achieving the correct gauge is crucial for ensuring your coasters are the intended size (approximately 4.5 inches square). If your gauge is off, adjust your needle size accordingly. A looser gauge will result in larger, drapier coasters, while a tighter gauge will produce denser, stiffer ones.

Step-by-Step Instructions

This pattern is worked flat, back and forth, and each coaster is identical. The construction is straightforward: you'll begin with a garter stitch border, work the intricate fern lace chart in the center, and finish with another garter stitch border before adding a crochet edge. Follow these detailed instructions carefully, and you'll have a beautiful set of four coasters in no time.

Abbreviations

• K: Knit
• P: Purl
• K2tog: Knit two stitches together (decrease)
• SSK: Slip, slip, knit (slip two stitches knitwise, one at a time, then knit them together through the back loop – a left-leaning decrease)
• YO: Yarn over (creates an increase and a decorative hole)
• PM: Place marker
• RM: Remove marker

Coaster (Make 4)

Step 1: Cast On
With your Main Color (MC) yarn, cast on 30 stitches using your preferred method (long-tail cast on is recommended for a neat, stretchy edge).

Step 2: Garter Stitch Border (Rows 1-4)
Knit all stitches for 4 rows. This creates a solid, textured garter stitch border that will frame the lace pattern beautifully. This border prevents curling and gives the coaster a finished, polished look.

Step 3: Begin the Fern Chart (Row 5 - Right Side)
Knit 3 stitches (this is your left border), place a stitch marker (PM), then work Row 1 of the Fern Chart across the next 24 stitches, place another marker (PM), and knit the final 3 stitches (your right border). The markers will help you keep track of the chart pattern without accidentally knitting into the border.

Step 4: The Fern Chart (Worked over 24 stitches)
The Fern Chart is the heart of this pattern, creating a delicate, lacy leaf motif through a combination of yarn overs and decreases. Work the chart rows as follows, remembering that all even-numbered rows are purled across all 24 stitches between the markers.

• Row 1 (RS): K1, YO, SSK, K6, K2tog, YO, K2, YO, SSK, K6, K2tog, YO, K1

Important Note on Stitch Count: As you work the chart, you'll notice that the yarn overs increase the stitch count. By the time you finish Row 39, you will have 40 stitches on your needles (the original 30 plus 10 increases from the yarn overs). This is intentional and creates the widening leaf shape. Do not panic if your stitch count grows; this is the magic of lace knitting.

Step 5: Wrong Side Row (Row 40)
Purl all stitches across the entire row (including the border stitches). This row stabilizes the lace pattern and prepares for the final border.

Step 6: Garter Stitch Border (Rows 41-44)
Knit all stitches for 4 rows. This mirrors the bottom border and frames the completed fern motif.

Step 7: Bind Off
Bind off all stitches loosely in knit on the right side. A loose bind-off is essential to prevent the top edge from pulling in and distorting the square shape. You can use a larger needle to bind off if you tend to knit tightly.

Step 8: Finishing & Blocking
Weave in all loose ends with a tapestry needle. To enhance the lace pattern and ensure your coaster lies perfectly flat, lightly block each piece. To block, soak the coaster in lukewarm water with a drop of mild soap, gently squeeze out excess water (do not wring), and lay flat on a towel. Pin it to the desired 4.5-inch square shape and allow it to dry completely. Blocking opens up the yarn overs and gives the coaster a professional, polished finish.

Step 9: Adding the Contrast Border
Once your coaster is dry, it's time to add the crisp cream white edge. With your Contrast Color (CC) yarn and a 4.0 mm crochet hook, work a round of single crochet (sc) evenly around the entire edge of the coaster. Work 3 single crochet stitches into each corner to ensure the corners lie flat and are nicely defined. Join with a slip stitch to the first single crochet. Fasten off and weave in the ends.

Step 10: Repeat
Repeat all steps to create a total of 4 coasters. Once all are complete, you'll have a beautiful, cohesive set ready to grace your table or to give as a heartfelt, handmade gift.

Enjoy your new Frosted Fern coasters! They are sure to bring a touch of winter woodland charm to every cup of tea or coffee.
