Make the complete long sleeve visible in costing
A ribbed long-sleeve top uses full sleeve panels whose direction, shaping and end finish can alter the marker. Obtain the actual body, sleeve and neck components, with separate cuffs only if the design includes them. The wrist is not simply the end of an extended tank pattern. If the approved elbow or upper-arm fit changes, send the revised sleeve to the cutter before comparing material quantities. A low body-only estimate cannot describe the accepted top when its sleeve pieces, direction rules or cuff package are still missing.
Use exact listed weights rather than an invented match
FR-401 fine rib lists 95% cotton and 5% elastane, Silicone + compacted, at 230, 250, 270, 290 and 310 g/m². RB-302 2×2 rib has the same blend with Enzyme + compacted at 220, 240, 260, 280 and 300 g/m². Although their ranges overlap, no listed option is identical. A nearby-weight comparison changes mass along with construction and finish. Request the offered weight, tolerance and usable cutting width for each actual proposal. Do not use a maximum stretched width observed by hand as a confirmed marker specification.
Show the effect of a local sleeve-width revision
For hypothetical arithmetic only, suppose a pattern proposal adds an average 0.02 metres of width along 0.50 metres of each of two sleeve panels. The simplified added area is 0.02 square metres in total. At 250 g/m² that represents about five grams before cutting and other allowances. These dimensions are invented, not an AL KUMAŞ sleeve recommendation or yield. The real curved panels require their actual area and marker assessment. This example shows how a local ease revision can have a bounded material consequence rather than justifying an unexplained increase across the entire top.
Give the cutter the approved rib orientation
Mark the intended rib direction on body, sleeves and any cuff or band, with the actual direction restrictions supplied by the design and technical team. A turned sleeve piece may nest attractively while changing the visible texture and fit proposal. If the cuff deliberately runs in another direction, record that choice rather than allowing the cutting room to decide from spare space. Ask the marker maker to show how the relevant adult sizes fit at the confirmed usable width. The layout should reproduce the selected orientation, not stretch or rotate components solely to meet an early target yield.
Separate sleeve-end options as different component requirements
A self-turned sleeve hem and a separately attached cuff can use different cut areas, materials and operations. Request the actual cut dimensions, layers, component count and joining rules for the accepted version. If the cuff uses another article or supply format, calculate its requirement separately and identify the commercial unit. Do not automatically price it as free offcut material. A revised sleeve-end opening also needs the technical team’s acceptance; shortening or narrowing it to recover a small costing difference can change the dressing and alignment decision that selected the sample.
Keep dimensional planning traceable to the sleeve landmarks
Request the relevant article and component evidence under the proposed care procedure, and ask how the pattern accounts for the results. CottonWorks identifies construction, processing, sewing and care influences on dimensional behaviour, without giving a sleeve allowance for either rib article. Document whether sleeve length, elbow registration or cuff relationship has already been adjusted in the pattern. Keep that decision separate from marker loss and order contingency. A general percentage applied twice cannot establish where the cared elbow and wrist should sit, even if the total purchased weight appears conservative.
CottonWorks: Shrinkage & Skewing — Construction, manufacturing and care affect dimensional behaviour; no specific FR-401/RB-302 top result or allowance is supplied.
Compare the accepted top with its actual sleeve package
The cost sheet should identify article, offered weight, finish, confirmed width, body and sleeve revisions, size mix and neck or cuff components. Label marker-based quantities and provisional assumptions. If an alternative rib requires a different approved sleeve shape, calculate that actual proposal rather than applying the first pattern’s yield automatically. Keep body and cuff price units explicit, comparing each proposal on the same commercial and delivery basis. Revisit the calculation after an alignment or elbow-ease change, so purchasing can understand the material consequence of the top being approved rather than choose a cheaper quantity belonging to an earlier rejected sleeve.
Technical background and scope
This is a structured editorial draft. Garment-specific development advice is paired with existing catalogue records; compatibility must be established by sampling. AL KUMAŞ supplies fabric. Cutting, sewing and finished-garment production are separate unless explicitly agreed.
