Can you make this jogakbo panel from the fabric you already own?

A fixed pattern cannot answer that. It was drawn for a window you do not have and a stash that is not yours. Enter the finished size you need and list the fabric actually sitting in your basket: you get the layout, a cutting chart with the seam allowance already added, and a diagram showing exactly where on each piece of your own fabric every cut goes.

Step 1

Your panel

Added to all four sides of every piece. A flat felled pojagi seam usually takes a quarter inch.

Your largest usable scrap

No piece in the plan will be bigger than this, so the layout is one you can actually cut.

How it works

Three pages free, three more when you list your fabric

  1. The layout. The whole panel drawn to one scale with every piece numbered by column and position.
  2. The cutting chart. Each numbered piece with its cut size and its finished size. The cut size already includes your seam allowance on all four sides.
  3. The sewing order. Piece each column top to bottom, then join the columns left to right. Every seam is straight, so a flat felled or French seam works throughout.
  4. The fabric map. The same layout with your own fabric names written into every piece, so you can see the panel before you cut it.
  5. A cutting diagram per piece of fabric. Each piece of your fabric drawn to scale with the cuts laid out on it, in the order to cut them, and the percentage of it you use.
  6. The fabric summary. Which fabric each piece comes from, how much is left over, and any seam where the same fabric ended up on both sides.

Column widths and row heights are chosen at random within your scrap limit and rounded to the nearest eighth of an inch or half centimetre, then adjusted so the pieces still add up to exactly the finished size you asked for. Each plan carries a seed; regenerating with the same seed reprints the same chart. The PDF is generated in this tab and nothing is uploaded.

FAQ

Before you cut

Is this free?

Yes. This version has no payment and no account.

Is this a traditional jogakbo layout?

It is a strip-pieced interpretation. Columns of irregular rectangles are the most common machine-sewable structure and the one that keeps every seam straight. Historical jogakbo also uses pieces that meet at odd angles, which this version does not generate.

How does it know my fabric is enough?

Every cut rectangle is placed on a specific piece of your fabric, one at a time, with the space left behind tracked as the strips a rotary cutter actually leaves. Nothing overlaps and nothing runs off an edge. If a piece has nowhere to go, you are told which piece and what size of fabric would fix it.

Can I use it with only small scraps?

Yes, within reason. Enter your largest scrap and the plan will never ask for a bigger piece. If the scrap is too small to leave a sewable piece once two seam allowances are removed, the tool says so instead of producing a chart you cannot cut.

Does the chart account for shrinkage or fraying?

No. Prewash and press before you cut, and add to the seam allowance if you are working with a loose weave such as ramie.
