Purse frames close a bag opening with a metal or wood frame instead of a zipper. On 3DANsupplies, many frames are labeled Sew-In, Glue-In, or Screw-In in the product title. That label tells you how the bag body attaches to the frame.
This guide compares sew-in and glue-in frames for clutches, coin purses, and structured bags. It also covers how to read titles, how to measure length, and how lock styles differ. Browse the full range in Purse Frames & Hinges.
What sew-in and glue-in mean on a purse frame
Sew-in frames have a sewing channel or flange with holes (or a clear sewing path) along the frame edge. You stitch the bag fabric or lining into that channel so the body is held by thread. In this catalog, many sew-in styles are listed as sew-in kiss-lock frames.
Glue-in frames use an adhesive channel. The bag edge sits inside a U-shaped or similar channel and is bonded with bag or leather adhesive. Product types on the site often call these glue-in (channel) kiss-lock frames. There is usually no sewing flange for a full stitch-in install.
A third label you will see is Screw-In (or screw-on). Acrylic and some wood-bead frames use screws to clamp the cover into the frame. Treat screw-in as its own method: check the product page for hardware included and hole placement before you cut your pattern.
When sew-in is the better fit
Sew-in fits well when your pattern calls for stitching the body into the frame, or when you are making fabric bags and lined soft clutches. It also helps when you want a join you can restitch for samples or repairs. Look for Sew-In in the title and a sewing channel in the photos.
Typical sew-in examples in this collection include rectangle, arch, and half-round sew-in kiss-lock frames in inch and metric sizes. Coin-purse and small clutch patterns often specify sew-in for that reason.
Match cover thickness to the channel depth shown on the product page, and follow your pattern’s seam allowances.
When glue-in is the better fit
Glue-in fits when the frame is labeled Glue-In or Glue-On and has an adhesive channel with no sewing holes. It also fits stiff covers—structured vinyl, card-backed fabric, and similar materials meant to sit in a channel—and wood-bead or heavy kiss-lock frames sold as glue-in sets.
Catalog examples include rectangle and half-round glue-in kiss-lock frames, wood-bead glue-in kiss-lock sets, and some push-lock clutch frames marked glue-in. Acrylic frames may say Glue-On; the idea is the same: bond into the channel rather than stitch through a flange.
Use an adhesive rated for your materials and allow full cure time before loading the bag. Do not force a glue-in-only frame into a sew-in pattern without redesigning the opening edge.
How to read a product title for install type
Start with the words near the front of the title:
- Sew-In — stitch into the frame channel or flange.
- Glue-In / Glue-On — bond into an adhesive channel.
- Screw-In / Screw-On — clamp with screws (common on some acrylic and wood-bead styles).
Then note shape and lock words: rectangle, arch, half-round, kiss-lock, push-lock, doctor bag, wood, acrylic. Size usually appears next as inches, centimeters, or both (for example, 10 3/4" (27 cm) or 26.5 cm).
If the title does not name an install method, open the product photos and description. Look for sewing holes versus a plain U-channel. Search within Purse Frames & Hinges for Sew-In or Glue-In when you already know the method your pattern needs.
Measuring frame length vs bag opening
Frame length on listings is the opening span of the frame, not the finished bag height. Compare that length to the bag opening width in your pattern.
Measure the frame opening (inside length of the mouth) and match it to the pattern’s stated frame size. Many titles list both inches and centimeters; use the same unit as your pattern. For two-dimension sizes such as 10" x 3 1/2" (25.5 x 9 cm), the first number is usually the main opening length—confirm on the product page if your pattern also needs depth.
Account for seam allowance and channel thickness. A frame that matches the cut opening on paper can still be tight once fabric fills the channel. If you are between sizes, prefer the size the pattern names. Changing frame length usually means redrawing the top edge of the bag.
Kiss-lock vs push-lock vs internal-hinge doctor-bag frames
Install method (sew-in vs glue-in) is separate from how the frame opens and closes.
- Kiss-lock frames use a ball or clasp pair that presses together at the top. Many sew-in and glue-in metal frames in this catalog are kiss-lock styles.
- Push-lock frames use a latch or tongue you push to open or close. Rectangle push-lock clutch frames appear in the collection, including glue-in variants.
- Internal-hinge doctor-bag frames use a wire or tubular frame with an internal hinge for a flex opening. These sit in the doctor bag / tubular & flex type group and suit structured doctor-bag shapes rather than small coin-purse kiss-locks.
Wood frames may use push locks, chain loops, or other closures without a metal kiss-lock. Pick lock style for the bag silhouette first, then confirm sew-in, glue-in, or screw-in for the cover. See styles side by side in Purse Frames & Hinges.
Matching loops, D-rings, and chain tabs to straps
Some frames include chain loops, D-ring loops, or fixed handles in the title. Those tabs are where a shoulder chain or strap attaches.
If the frame lists chain loops or D-rings, you can add a chain or strap without sewing separate anchors into the bag body. Match finish (nickel, antique bronze, gold, and similar) to nearby hardware when possible. For replacement or custom straps, browse Straps & Chains. For rigid or paired handles that pair with framed bags and totes, see Bag Handles.
Confirm loop opening size against your chain width or clasp before cutting strap length. Frames sold with handles already attached may not need a separate strap purchase.
What to open next
Open Purse Frames & Hinges. Scan titles for Sew-In, Glue-In, or Screw-In to match your pattern. Pick shape and lock type (kiss-lock, push-lock, doctor-bag, wood, acrylic). Choose length and finish on one product page, and verify channel style in the photos. Add straps, chains, or handles only after the frame size and loops are set.
