This original sphere study grows through four six-sector rounds, holds the widest count for three more rounds and reduces back to six stitches. Its ten worked round counts are six, twelve, eighteen, twenty-four, twenty-four, twenty-four, twenty-four, eighteen, twelve and six. Their sum is 168 single-crochet outputs. The final tail drawn through six front loops is a sewing closure, so it does not add another six stitches to that workload.
Count old bases at a decrease
The first reduction consumes twenty-four old stitches in six groups of two ordinary single crochets followed by one decrease. Each group consumes four bases and produces three stitches, leaving eighteen outputs. The next reduction consumes groups of three bases and produces two, leaving twelve. The last consumes paired bases to make six. In the source chart, two incoming anchor lines meet each decrease symbol. Counting those two old bases as two new stitch tops would conceal the actual reduction.
Assess the physical volume after the arithmetic
Three even rounds add depth without widening the shell. Their apparent contribution depends on stitch and round gauge, yarn elasticity and filling pressure. Add stuffing before the last reductions restrict access, then close and finish a real sample before recording diameter. The generator's source-connected loop view explains the construction, but it cannot certify a mathematically perfect sphere or a particular finished size from the round count alone.
Questions and repairs
Why do I count four rounds at twenty-four?
The last increase round already reaches twenty-four. Three additional even rounds make four consecutive occurrences.
Should I join every round?
No. This study is a continuous spiral with a moved first-stitch marker and no routine joining slip stitch.
Can extra filling correct a missing increase?
Recount and repair the affected round. Stuffing can stretch fabric but cannot restore a missing stitch or its proper insertion source.
Exact setup, stitch key and complete sequence
Open the Amigurumi Shape Planner, choose sphere, set growth rounds to 4 and even rounds or shaft length to 3. Download the exact original project JSON before editing it. Use smooth compatible yarn, a hook giving firm fabric, removable markers, suitable filling and a tapestry needle. The swatches identify component yarn roles; they do not assign a different yarn to every round unless a row explicitly says so.
In US terms, sc means single crochet, an increase works two sc in one old base and sc2tog consumes two bases to make one stitch. In UK mode those become dc and dc2tog without changing source coordinates or counts. Mark the first stitch of each separate spiral and move the marker after every completed circuit; do not add joining slip stitches or turning chains. Follow each part's own start, final rim and closure. Make the stated number of copies, then execute any separate attachment rows. Read the amigurumi shaping guide and compare the actual fabric after filling. The diagram is a counted construction reference; physical size, bend angle and finished suitability need a real sample. Finish every tail securely before handling the completed form.
Every worked round and attachment step
Sphere (make 1), round 1, base yarn #678591: Magic ring: ch 1 (not counted), 6 sc. Tighten ring and mark first stitch. Continue in a spiral without joining or turning. [6 outputs per copy]
Sphere (make 1), round 2, base yarn #678591: Repeat [0 sc, 2 sc in next stitch] 6 times. Each increase makes two stitches in one old base. [12 outputs per copy]
Sphere (make 1), round 3, base yarn #678591: Repeat [1 sc, 2 sc in next stitch] 6 times. Each increase makes two stitches in one old base. [18 outputs per copy]
Sphere (make 1), round 4, base yarn #678591: Repeat [2 sc, 2 sc in next stitch] 6 times. Each increase makes two stitches in one old base. [24 outputs per copy]
Sphere (make 1), round 5, base yarn #678591: Sc once in each old stitch; move the first-stitch marker. [24 outputs per copy]
Sphere (make 1), round 6, base yarn #678591: Sc once in each old stitch; move the first-stitch marker. [24 outputs per copy]
Sphere (make 1), round 7, base yarn #678591: Sc once in each old stitch; move the first-stitch marker. [24 outputs per copy]
Sphere (make 1), round 8, base yarn #678591: Repeat [2 sc, sc2tog over next two stitches] 6 times. Each decrease consumes two old bases and makes one stitch. Add filling before the opening becomes too small. [18 outputs per copy]
Sphere (make 1), round 9, base yarn #678591: Repeat [1 sc, sc2tog over next two stitches] 6 times. Each decrease consumes two old bases and makes one stitch. Add filling before the opening becomes too small. [12 outputs per copy]
Sphere (make 1), round 10, base yarn #678591: Repeat [0 sc, sc2tog over next two stitches] 6 times. Each decrease consumes two old bases and makes one stitch. Add filling before the opening becomes too small. Fasten off; pass the tail through the remaining six front loops, draw closed and conceal the tail. This sewing closure adds no crochet round.
