What Is Quiltler Block Invert?
Quiltler Block Invert is an original two-colour block built entirely from curved shapes. Its 32 pieces are divided evenly between 16 Drunkard’s Path pieces and 16 Drunkard’s Path Invert pieces. Alternating the two shapes produces the repeated opposing curves that define the design.
The block uses Fabric 1 and Fabric 2 throughout the arrangement. The contrast between those fabrics makes the direction of each curve and the larger order of the block easier to read. You can view this design alongside other ideas in the quilt block index, but its specific measured layout opens from the design page.
How the Curved Pieces Go Together
Each curved pair needs controlled handling. Match the centres and ends of the opposing curves before easing the remaining edges together. This distributes the curve rather than forcing one section to absorb the difference. Work carefully around the concave piece so that small tucks do not form.
The curved edges include bias, so avoid pulling or stretching them as you match and sew. After completing the curved units, press them consistently and check their alignment. Assemble the checked units into rows, then join the rows to complete the block. Following the same handling and pressing approach for every unit helps the repeated curves stay ordered across the finished square.
Because all 32 pieces are shaped, small inconsistencies can carry from one unit into the next. Pause to inspect each unit before adding it to a row. If an edge has stretched or a tuck has formed, correcting it before row assembly is easier than trying to adjust the complete block.
Finished Size, Use and Skill Level
The finished block measures 12 inches by 12 inches. That measurement describes the completed block rather than the size of a whole quilt. You can use it as a single design element or repeat it when planning a larger layout, including a bed quilt. The finished bed size will depend on how you arrange and repeat the block in your project.
This design has been judged advanced because every piece is curved and the layout alternates standard and inverted Drunkard’s Path shapes. It best fits a quilter who is comfortable matching curved sections, easing edges without stretching them and checking alignment during assembly. The repetition gives you a consistent process, but it also makes uneven curves or pressing easier to notice.
If you are deciding how the block might work within a larger plan, the how to design quilts guide covers the broader design process. You can also browse the gallery for more ideas about colour, repetition and overall quilt layouts.
Recolour the Two-Fabric Design
Open Quiltler Block Invert to replace Fabric 1 and Fabric 2 with colours or fabric images from your own plan. Since the block uses only two fabrics, each change affects a clear part of the repeated curved arrangement. Try reversing the visual roles of the fabrics to see how the opposing curves read when the balance changes.
Look at the block as a whole while you recolour it. Contrast can make the alternating shapes more visible, while a quieter relationship can soften the boundaries between them. Quiltler lets you compare those choices on the measured design before you settle on a version to sew.
If you are working from fabric you already own, you can photograph your stash and use those images while planning. For a separate estimate, open the quilt fabric calculator and enter the details for the project you intend to make.
Resize and Plan the Block in Quiltler
The saved design is a finished 12-inch square, matching the authoritative measurement shown on this page. In the Quiltler studio, you can explore a resized version if your project calls for a different block scale. Keep in mind that resizing changes the dimensions of every curved piece, so review the resulting design rather than assuming the original handling will feel identical.
When you resize, preserve the square proportions if you want to retain the same overall arrangement. Check the updated fabric information and make sure the new scale is appropriate for how you plan to prepare and sew the opposing curves. Quiltler gives you a visual place to compare size and colour choices before working with fabric.
You can also return to the original live design at any point. Keeping the measured 12-inch version available gives you a clear reference as you compare recoloured or resized alternatives.
Sew this block in Quiltler
Use the live Quiltler design to inspect the original block, test fabrics and prepare a version for your project.
- Open the measured block Open Quiltler Block Invert to load the finished 12-inch square with its 32 shaped pieces.
- Review the curved arrangement Inspect how the 16 Drunkard’s Path pieces alternate with the 16 Drunkard’s Path Invert pieces. Note where each opposing curve meets before changing the design.
- Choose the two fabrics Replace Fabric 1 and Fabric 2 with the colours or fabric images you want to compare. Watch how each choice changes the visibility of the ordered curves.
- Test a resized version Adjust the block size if your project requires a different scale. Preserve the square proportions when you want the original arrangement to remain unchanged.
- Check the updated requirements Review the live fabric information after recolouring or resizing. Return to the original 12-inch version when you need to compare your changes with the measured design.
- Prepare for curved assembly Use the displayed arrangement as a reference while organizing the opposing pieces. Match centres and ends, ease the curved edges, press consistently and check units before assembling rows.
Photograph fabrics from your own stash and watch the fabric requirements update as you adjust the design.
