OLFA RM-SG 18 x 24in Double-Sided Self-Healing Rotary Mat

$51.50

The everyday size that fits real sewing spaces

Room to cut confidently without taking over the table

The OLFA RM-SG gives quilters, sewists and crafters an 18 x 24 inch imperial cutting grid in a practical mid-size format. It is large enough for long quilting rulers, blocks, strips and fat quarters, yet easier to place and store than a full-size studio mat.

  • 18 x 24 inch cutting grid handles everyday patchwork and sewing without a huge footprint.
  • Two usable cutting faces give you a yellow imperial grid on one side and plain green on the reverse.
  • Self-healing 1.5mm surface closes after normal rotary cuts to help the mat remain smooth.
  • Triple-layer heat-welded construction supports durable, reliable rotary cutting.

Why 18 x 24 inches is such a versatile size

The grid accommodates a standard 24 inch quilting ruler, while the overall mat remains manageable for many dining tables, sewing desks and shared workspaces. It is a smart balance of useful cutting room and easy day-to-day handling.

Long strips and borders

Support a 24 inch ruler for binding, quilt strips, borders and straight fabric cuts.

Blocks and fat quarters

Trim medium and larger blocks or work through fat quarters without the restriction of a tiny mat.

Everyday convenience

Keep a capable cutting surface ready without committing an entire studio table to a full-size mat.

A smoother place for every rotary cut

Self-healing layers protect both the table and the blade

OLFA's heat-welded triple-layer construction combines soft self-healing cutting faces with a supportive centre. Fine lines from normal rotary cuts close back together, helping the mat stay smoother while supporting longer blade life.

Gridded cutting face

Yellow imperial markings support accurate measured cuts with quilting rulers and templates.

Plain green cutting face

Turn the mat over for general rotary cutting, plush fabric or batting where loose fibres may obscure the grid.

Two sides share the wear

Using both cutting faces spreads projects across more of the mat and helps preserve the printed guides.

Correct storage prevents permanent warping

Self-healing does not mean heat-proof or warp-proof. OLFA states that a warped mat cannot be made flat again, so give it a cool, fully supported storage space.

  • Store the mat flat and never roll it.
  • Keep it away from direct sunlight and extreme temperatures.
  • Do not leave it in a hot or cold vehicle.
  • Never iron on the mat or place hot tools on it.
  • Clean with mild detergent on a soft, damp cloth.
  • Move repeated cuts around the surface to avoid permanent grooves.
  • Use a lint roller, heavy tape or art gum eraser to lift trapped fibres.
  • Keep pins, needles and loose objects clear of the cutting path.

OLFA RM-SG FAQs

Which exact RM-SG is this?

This listing is for the original OLFA RM-SG, item 9881, matching Direct Sewing SKU RMSG9881.

Is the mat double-sided?

Yes. Both faces can be used for rotary cutting. One side has a yellow imperial grid and the other is plain green for general cutting.

Does it have a centimetre grid?

No. The printed grid is imperial and measures 24 x 18 inches. The approximate overall mat size is 63 x 47cm.

Is 60 x 45cm the complete outside size?

No. That is the approximate metric equivalent of the working grid. The full mat is approximately 63 x 47cm, while the printed grid is 24 x 18 inches.

Can I use an art knife or utility knife?

No. OLFA specifies the RM-SG for rotary blades only. A fixed blade can cut too deeply and permanently damage the surface.

Does self-healing mean cuts disappear completely?

The surface is designed to close after normal rotary cuts so fine lines become much less visible. Repeatedly cutting the same place can still create a permanent groove.

Can I iron on the mat?

No. Heat can permanently warp the mat. Keep irons, hot tools, direct sunlight and extreme temperatures away from it, and always store it flat.

What is included?

One genuine OLFA RM-SG green double-sided self-healing rotary mat. A rotary cutter, ruler, fabric and other project materials are not included.
