Frequently asked questions
Answers about materials, pin counts, printing, saved designs, voice guidance, thread repairs, and physical results.
What frame size should I start with?
A 50–60 cm (20–24 inch) circle is a practical starting point. A 30–40 cm frame suits simpler designs; an 80 cm or larger frame requires more space and can suit detailed work once you have experience.
How many nails do I need?
The guide suggests 150–200 for simple shapes and icons, around 250 for many images, and 300 or more for fine portraits. More evenly spaced pins offer more possible connections, with diminishing returns. They also take longer to install and number. Fine text remains difficult.
Which thread works best?
Start with strong, fine polyester thread. The original guide suggests 50wt, roughly 0.2 mm, but weight and diameter are not interchangeable specifications. Check the actual product. Thick or fuzzy embroidery floss can hide fine detail; weak thread can break under tension.
How long does assembly take?
The original guide estimates 2–4 hours for 2,000–3,000 lines, 4–8 hours for 4,000–6,000 and 8–15 hours for 8,000–10,000. These are hand-stringing estimates, not generation times. Your pace varies; work over multiple sessions and take breaks.
Why is the preview unclear?
Try a source with clearer contrast, crop around the subject and simplify the background. Increasing line count may add definition, but can also make dark areas too dense. Compare previews before building.
What does string count mean?
It is the number of nail-to-nail connections, not separate pieces of thread. More lines often darken the result and take longer to string. The guide uses 4,000–6,000 as a broad starting range; choose based on your preview.
Can I save and continue later?
Save Design stores your image, settings and generated sequence in your account. A free account is required. Record your physical progress as well so you can resume at the correct connection.
How does Voice Guidance work?
After generation, enable Voice Guidance in the sequence panel. It reads the sequence so you can keep your eyes on the work. Select language and voice options and adjust speaking speed using the available controls.
Why do nails bend?
Keep the hammer face parallel to the nail head, hold the nail with pliers and try pilot holes in hard wood. Use appropriate 1–1.25 inch finishing nails rather than unnecessarily long nails. Poor-quality nails may bend more easily.
Why is the printed template the wrong size?
Set printing to 100% or Actual Size and disable Fit to Page, Shrink to Fit and similar scaling. On a Mac, check Scale: 100%. Print a test sheet and measure a known dimension. Check margins as well.
How can I spot a sequence mistake?
Unexpectedly empty or dense areas, a mismatch with the preview or losing your place can indicate a missed connection. Use the numbered pins to find your position, then carefully unwind and redo the recent incorrect lines.
Can I use regular sewing thread?
Some ordinary sewing threads are too thick for fine detail, but product labels vary. Choose by actual diameter and strength rather than the word “sewing.” The original guide favors fine 50wt polyester or cotton-wrapped polyester over thick or fuzzy thread.
Why is the pattern too light or dark?
More lines generally make it darker; fewer lines or thinner thread make it lighter. A clearer source image can help. Match the thickness setting to your real thread and compare the new preview.
What if I run out of thread?
Record the current connection. The original guide describes tying off and starting new thread at that same nail. That is a physical repair, not an uninterrupted strand; if one unbroken thread is required, plan sufficient thread before starting. Keep any knots secure.
How do I repair a break?
Hold the ends to prevent unwinding. A secure knot near a nail can join them, or you can anchor and restart at that nail. Trim excess carefully. Repairs may remain visible and introduce a join; an unbroken-thread requirement cannot be met by a repair.
Why does the finished piece differ from the preview?
Check the exact nail count, numbering, starting position and thread thickness. Also check wrap instructions and tension. Small differences between a rendered preview and physical material are possible.
How does color mode work?
Color mode selects line and thread-color combinations to improve the image. Follow the color changes shown in its sequence; changing color requires extra physical work. The guide suggests 8,000–12,000 lines for color compared with around 3,000–6,000 for monochrome. Color changes are separate from the continuous black-thread workflow.
Can I use a non-circular frame?
The app offers Circular and Rectangular frame controls. Use settings for the shape you will actually build. Do not assume hearts or arbitrary custom outlines are supported.
What is the largest frame?
Use the size limits currently shown by the app rather than assuming an unlimited template size. Larger patterns need more paper, sturdy board, more installation time, enough thread and a suitable mounting plan. Very large pieces need particular care with support and display.
How should I photograph the result?
Use diffused light to avoid glare, point the camera straight at the piece to reduce distortion, choose a contrasting background and capture enough resolution to retain thread detail.
