Terms of use
Quilt Block Atlas is free to use. Its cutting charts are computed, not copied, so you can check them yourself. Do check the first piece of each size against your ruler before you cut the rest.
Verify before a batch cut
The site gives the number; your ruler confirms the first piece.
Calculate. Start with the generated chart. If a size cannot be cut cleanly, use one of the sizes offered; do not round a rejected size.
Test one piece. Measure the first piece of each size against your ruler and confirm it.
Cut the batch. Once the first piece is confirmed, cut the rest. A printed pattern template still depends on a printer that does not scale the page.
Check before you cut
Every chart and calculator here is computed, not taken from a fixed list of sizes. A computed number is still met by a real ruler and a seam that runs a little wide or narrow. Measure the first piece of each size, confirm it, then cut the rest.
When a size cannot be cut cleanly, the chart or calculator says so. If the size is on your ruler but the grid cannot divide it, nearby clean sizes are offered instead. Use one of those. Do not round a rejected size to something that fits your ruler; the block will finish wrong.
Using the content
The charts, diagrams and guides are here for your own quilting. Print them and cut from them freely, for your own projects or a class you teach. Traditional block names identify the published designs. Histories, alternate names and attributions appear only once they have been verified, and each block history names its sources; the site's own text and code are the work of Quilt Block Atlas.
No warranty
The measurements are generated by tested formulas and given in good faith, but the site is offered as it is. It cannot guarantee a result in fabric, and it is not responsible for material cut to a size you did not check first. When a number matters, cut one piece and measure it.
