Round set: Crochet Coaster Set Generator

Establish a repeatable four-disk reference

This original set starts with the simplest receiving structure: a magic ring and six equally spaced growth sectors. Make four independent disks, each with round counts six, twelve, eighteen and twenty-four. The sixty single-crochet outputs in one disk become 240 across the set. No decrease, stuffing or closing cap belongs to this flat construction. The final twenty-four-position edge remains the outside perimeter rather than an opening to sew shut.

Audit the increase bases before making copies

Round two works two single crochets in each of six old bases. Round three repeats one ordinary stitch and an increase six times, consuming twelve bases and producing eighteen outputs. Round four repeats two ordinary stitches and an increase, consuming eighteen and producing twenty-four. Move the first-stitch marker after each circuit; the spiral does not require a joining slip stitch at every round. A final slip stitch softens the finish and is deliberately outside the sixty-output budget.

Match physical pieces to the first washed disk

Use the first completed disk as a reference after washing and drying it according to the actual yarn's care instructions. Compare the other three against its diameter, flatness and outside-edge tension. Four identical instruction sequences can still produce different sizes if tension changes. Adding a finishing round to only the smallest disk would change its saved specification, so first investigate gauge and missed increases.

FAQ and practical repairs

Can the round count guarantee a cup-sized coaster?

No. Compare the relaxed sample against the intended cup base and regenerate a supported larger size when needed.

Why is the edge cupping?

Recount all six increases and inspect tension. Arithmetic alone cannot establish flatness in every yarn.

Must the four disks be joined?

No. The final set instruction counts four separate finished pieces; it is not a seam or another crochet round.

Exact setup, terminology and saved source

Open the Coaster Set Generator and choose round. Set working rounds to four, quantity to 4, rectangular recipe width to twelve stitches and its length to twelve rows. Only controls used by the chosen recipe affect its construction. Download the exact original project JSON before changing colors or dimensions. Use compatible smooth yarn, a matching hook, removable markers, scissors and a tapestry needle. Make and wash a trial piece before repeating the full quantity.

The following complete sequence uses US terms: sc is single crochet, dc is double crochet, ch is chain and sl st is slip stitch. UK mode converts sc to dc and US dc to tr while retaining all insertion sources and counts. Starting chains, spaces, petal closures and routine joins follow each recipe's explicit counting convention; do not apply one blanket convention to every component. The chart-reading guide explains how to compare symbols with written instructions. Finish and weave every tail, then retain the measured sample and saved project together. These original vector diagrams show generated construction rather than a photographed or physically validated finished sample.

Complete component recipes and final set check

1. Plain spiral disk (make 4), round 1: Magic ring: ch 1 (not counted), 6 sc. Tighten ring and mark first stitch. Continue in a spiral without joining or turning. [6 counted outputs per copy]
2. Plain spiral disk (make 4), round 2: Repeat [0 sc, 2 sc in next stitch] 6 times. Each increase makes two stitches in one old base. [12 counted outputs per copy]
3. Plain spiral disk (make 4), round 3: Repeat [1 sc, 2 sc in next stitch] 6 times. Each increase makes two stitches in one old base. [18 counted outputs per copy]
4. Plain spiral disk (make 4), round 4: Repeat [2 sc, 2 sc in next stitch] 6 times. Each increase makes two stitches in one old base. Sl st in the next stitch to soften the spiral finish; this finishing slip stitch is excluded from sc counts. Fasten off, weave both tails securely and block the unfilled disk flat without stretching. [24 counted outputs per copy]
5. Keep these pieces separate; no seam joins the set. Finish every recipe as written. Wash and block a trial piece, compare the actual base of the intended cup, and repeat to the stated quantities. A larger table mat is not certified for hot cookware. [4 separate finished pieces]
