TRIMCRAFT
Finish it beautifully — sewing trims, notions, and haberdashery.
From converting fabric yardage and sizing a seam allowance to cutting bias tape, budgeting trim and ribbon, scaling a pattern, and estimating thread, TrimCraft pairs free hands-on sewing calculators with practical guides and a richly illustrated notions museum. Measure twice, sew once.
Sewing Tools & Calculators
Free tools for every project — fabric yardage calculator, seam allowance calculator, bias tape length, trim and ribbon quantity, pattern scaling, and thread consumption.
Fabric Yardage Calculator
Convert a pattern's stated yardage to the fabric width you're actually buying, with allowances for nap and print-repeat matching
Seam Allowance Calculator
Work out a piece's cut size from its finished size, seam allowance, and seam finish, plus the total cut length with a hem
Bias Tape Length Calculator
Size the binding for an edge, or work out the fabric square the continuous-bias method needs to produce it
Trim & Ribbon Quantity Calculator
Multiply a per-piece trim length across every item you're decorating, with a buffer for corners and mis-cuts
Pattern Scaling Calculator
Find the exact scale factor and copier/PDF percentage to resize a pattern to your own measurements
Thread Consumption Estimator
Estimate total thread from your seam lengths and stitch type, plus how many spools to buy
Notions & Haberdashery Museum
Wander an immersive museum of the small objects behind every garment — buttons and fasteners alongside lace and ribbon, trims and braids from around the world, and the history of the haberdashery notions that hold, close, and finish what we sew, each in its own gallery, so you can get to know the stories behind every notion: how it came to be, what makes it useful, and the role it plays on the sewing table today.

Fresh guides on fabric basics, seams and construction, trims and embellishment, pattern fitting, and notions and tools, plus the reasoning behind the numbers the calculators produce.
How to Convert Fabric Yardage Between Widths (Without Guessing)
A pattern's yardage chart is only correct for the width it was written for. Here's the ratio that converts it to your actual bolt, and when to add extra for nap and print repeats.
Seam Allowances Explained: Standard, French, and Flat-Felled
A seam allowance isn't just "extra fabric" — how much you need depends entirely on which seam finish you're sewing. Here's what standard, French, and flat-felled seams actually require, and why.
The Continuous Bias Tape Method, Step by Step
Cutting bias strips one at a time and joining the ends is slow and wasteful. The continuous-bias method turns a single square of fabric into one long spiral of tape — here's how it works.
How Much Trim Do You Really Need? Avoiding a Second Trip to the Notions Counter
Running short on ribbon or lace halfway through a project usually means a mismatched dye lot on the second trip. Here's how to measure accurately and buy the right amount the first time.
Pattern Scaling vs Grading: What's the Difference
Enlarging a pattern on a photocopier and grading it between standard sizes are not the same technique, and using the wrong one can quietly wreck a garment's fit. Here's how each actually works.
A Field Guide to Sewing Machine Needles and Thread
The wrong needle or thread for your fabric shows up as skipped stitches, snags, or puckering — usually blamed on the machine. Here's how to match needle, thread, and fabric correctly.
