Compare the BERNINA #31 5-groove and #32 7-groove pintuck feet on groove spacing, cord size, and fabric weight to choose the right foot for heirloom pintucks.
Quick answer
Choose the BERNINA #31 5-groove foot when you want slightly wider, more visible pintucks on lightweight fabrics, and the #32 7-groove foot when you need the finest, most closely spaced pintucks for delicate heirloom work.
Groove count changes spacing, not just width
The number of grooves determines how closely the rows sit together. The #31 has five grooves and the #32 has seven, so the #32 produces a denser band of pintucks while the #31 leaves a little more breathing room between rows. That difference matters most when you are covering a large area or working a small collar where too many rows would look crowded.
Cord size is a separate decision from groove count
Both feet guide previously sewn pintucks to keep rows parallel, but the cord you use fills the groove and sets the height. A thicker cord in a 5-groove foot gives a more pronounced ridge; a finer cord in a 7-groove foot keeps the texture subtle. Neither foot comes with a fixed cord, so test on a scrap of your actual fabric before committing to a full panel.
Fabric weight limits the finer option
The 7-groove foot is intended for delicate fabrics and intricate heirloom work. On heavier cotton or linen, the very fine spacing can become hard to see and the rows may crowd each other. The 5-groove foot is the more forgiving choice when you want pintucks to read clearly on lightweight but not ultra-fine material.
Trade-offs to weigh before you buy
- Spacing vs. subtlety: The 7-groove foot gives very fine, close rows; the 5-groove foot gives slightly more open, more visible rows. If you want the fabric to show a clear pintuck pattern, the 5-groove is easier to read.
- Cord size flexibility: Match cord thickness to the groove you use. A thicker cord in the 5-groove foot creates a stronger ridge; a fine cord in the 7-groove foot keeps the look delicate. Test both if you are unsure. Buy the foot that matches the cord you already own or plan to use most.
- Fabric weight match: The 7-groove is best on delicate fabrics; the 5-groove handles lightweight fabrics where you want the pintucks to remain distinct. Neither is intended for heavy fabrics.
Product facts
- #31 BERNINA Pintuck Foot 5-Groove: Five grooves create finer, more closely spaced pintucks than the 3-groove version. This makes it a middle ground for sewists who want visible texture without the extreme density of a 7-groove foot.
#31 BERNINA Pintuck Foot 5-Groove - #32 BERNINA Pintuck Foot 7-Groove: Seven grooves create the finest, most closely spaced pintucks in the pintuck foot family. This is the choice for heirloom sewing where subtle, refined texture is the goal.
#32 BERNINA Pintuck Foot 7-Groove
