Straight Seams Every Time, No Wandering Line
You know the moment. You press the finished seam flat, and there it is — the line drifted.
Not by much. Just enough that you can see it.
Seamkeep sits on your machine bed and holds the fabric's edge steady, so the seam stays where you put it.
The seam ripper tucks inside the guide body, blade stored away, so it's already there when you need it.
Straight runs, corners, curves, layered fabric — the guide stays put through all of it.
The ripper lives inside the guide — nothing loose in your basket
✓ Sews straight on curves and corners too
Most guides only handle a straight run. This one repositions in seconds, so your seam allowance stays even around a corner, along a curve, and through layered fabric.
✓ No more getting up mid-seam
Your ripper is in the drawer. Your ruler is on the other table. Seamkeep puts all three in one spot on the machine bed, so you stay in your chair and keep your rhythm.
✓ The blade stays tucked away until you need it
The seam ripper retracts into the guide body. No loose blade stabbing around your sewing basket, and no hunting for the cap you lost months ago.
✓ It lives on the machine, not in the gadget drawer
This isn't a tool you store and forget. It stays on the machine bed between projects, so it's in your hand the second you sit down.

Frequently asked questions
Will it work with my home sewing machine?
Yes. It sits on the flat machine bed beside the presser foot, so it works with standard domestic machines as well as heavier-duty ones. It's not tied to one brand or model.
Can I move it for different seam allowances?
You can. Lift it, slide it to the width you want, and set it back down. It takes a couple of seconds, so switching between a narrow hem and a wider seam is easy.
How do I get the seam ripper out?
It slides out from inside the guide body and locks in place for use. When you're done, push it back in so the blade is stored away.
Does it get in the way when I'm free-motion quilting?
No. Just lift it off the bed and set it aside. It's a single piece, so there's nothing to unscrew or reattach.
How to use
- Step 1: Place Seamkeep on the machine bed, to the right of your presser foot.
- Step 2: Slide it left or right until the edge sits at your chosen seam allowance. Use the inch or centimeter marks on the face.
- Step 3: Feed your fabric so the raw edge runs along the guide. Keep light pressure against it and let the machine pull.
- Step 4: For a corner or curve, lift the guide and reposition it, then continue. Takes about 1–2 seconds.
