Open mesh: Crochet Mandala Doily Generator

Follow the openings through two transitions

This four-round mesh study begins with twelve double crochets, opens a ring of twelve chain-two spaces, changes those to twelve chain-one spaces, and finally fills the ring. Its independent task is to distinguish post-top sources from chain-space sources at each transition. The last round is solid rather than another mesh repeat. The project verifies that sequence; it does not claim an all-over lace fabric or a physically tested flat doily.

Prepare a visible single-yarn reference

Use smooth fine cotton and begin with a two-and-a-half-millimeter hook. Have scissors, a tapestry needle, twelve removable repeat markers, a start marker and a ruler ready. Select Openwork center then solid, four total working rounds, Joined rounds and US terms. Both palette entries are blue #243BCE. The sector selector is inactive because this structure uses its specified twelve-opening schedule. Materials and hook size are trial choices, not measured evidence of the final openness or diameter.

Produce twelve chain-two openings

Work twelve double crochets into a magic ring, excluding the starting height chain. Join to the first actual post. On round two, work one double crochet into each old post and chain two after it. Join to the first new double crochet. There are twelve post tops and twelve arches formed from twenty-four chains. Twelve post tops plus twelve arches are twenty-four different possible sources, but the next round deliberately uses only the arches.

1. Magic ring: ch2 (not counted),12 dc. Sl st to first actual dc. Count 12 completed stitches or units.
2. Ch2 (not counted). In each old dc work dc, ch2. Join to first dc. Twelve dc and twelve ch-2 openings. Count 12 completed stitches or units.
3. In each old ch-2 opening work2dc, ch1. Starting ch2 is not counted; join to first dc. Twenty-four dc and twelve ch-1 openings. Count 24 completed stitches or units.
4. Ch2 (not counted). Repeat [dc in each of two old posts, dc in following ch-1 opening] twelve times. Join to first dc. Thirty-six dc; all twelve openings filled once. Count 36 completed stitches or units.

Change both stitch count and arch length

In each chain-two opening, work two double crochets and chain one. Join the circuit to its first actual post. Round three therefore has twenty-four double crochets and twelve chain-one openings. Do not also work into the twelve old post tops from round two. Those are visible beneath the work, but are not additional sources in this transition. Keep one marker per opening while checking that every original arch was used exactly once.

Fill every current source once

Round four repeats one double crochet into each of two old post tops, then one double crochet into the following chain-one opening. Twelve repeats consume twenty-four old post tops and twelve arches, producing thirty-six posts. There are no new spacing chains. The source chart gives these two kinds of insertion separate identifiers, so a post mistakenly worked around a gap can be traced instead of being hidden by a correct-looking final total.

Audit counts without merging categories

The post counts twelve, twelve, twenty-four and thirty-six sum to eighty-four double crochets. Round two supplies twenty-four spacing chains, and round three supplies twelve, for thirty-six chains in their separate budget. Starting-height chains and joining slip stitches are excluded. The number of openings remains twelve during both mesh rounds even though the arch length and post count change. Counting individual chains as openings would create the wrong number of repeat sources.

Inspect before extending the filled edge

Can another mesh round be assumed from this record? Later working rounds in this option continue solid twelve-increase expansion, so a new openwork repeat needs a separate specification. Does a filled edge guarantee the center stays open after washing? Inspect an actual sample without stretching the windows into shape. Weave the ends and record relaxed size and drape beside the artifact. The motif design guide explains why consistent insertion counts and physical fabric behavior answer different questions.
