Plastic Elliptic Boning 1.8mm x 1.5mm - By the Yard

Plastic Elliptic Boning 1.8mm x 1.5mm - By the Yard

Our Plastic Elliptic Boning - 1.8mm x 1.5mm is a premium European-made plastic boning, also known as synthetic whalebone or plastic whalebone. Like our 3.2mm x 2.25mm elliptic boning, this boning has an elliptic (oval) cross-section that allows it to flex in multiple directions rather than a single plane - but at a narrower, more delicate profile it delivers an even softer hand, making it the right choice for lightweight and fine-fabric applications where any visible structure would be unwanted. Slightly more flexible than our flat German Plastic Boning, it provides just enough support to keep edges crisp and panels in place without adding stiffness or bulk.

This boning can be cut with sturdy scissors and the cut edge finished with a nail file - no specialty tools required. It is safe to dry clean or machine wash; air dry only.

Usage & Application

• Cut to length with sturdy scissors and smooth any cut edge with a nail file before use - no bone tips required
• Insert into underwire channeling as a softer, lighter alternative to traditional underwire in bras, bikini tops, and lightweight bodices
• Encase in any seam allowance to add subtle structure along a seam line without a separate channel
• Use with a piping foot and zig-zag stitch to secure alongside fabric edges
• Sew a bias strip to a hem edge and insert the boning to create a gently shaped or wavy decorative hem in fine or lightweight fabrics
• Use in curved or shaped seams in delicate fabrics where flat boning would distort the line
• Well suited to bra cups, bra side panels, bikini tops, and fine lingerie where the most minimal, discreet structure is needed
• Suitable for fascinator accessories and fine millinery where a narrow, flexible bone holds a shaped edge without adding visible bulk

Pro Tip: At 1.8mm x 1.5mm this is the most discreet boning in our range - fine enough to disappear into lightweight fashion fabrics including silk, chiffon, and charmeuse. Use a piping foot and zig-zag alongside the fabric edge to secure it cleanly without stitching through. The needle will deflect or break if you attempt to sew through the boning directly.

Pro Tip #2: For shaped fascinator brims or decorative costume edges in fine fabric, sew a narrow bias strip to the hem and insert a length of this boning before closing the strip. The result is a controlled, structured wave that holds its shape without stiffening the fabric.
