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.

Rotary cutter, ruler, fabric and other project materials are not included. A useful upgrade from a small starter mat 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. Choose the size and surface that match the job Ideal for everyday rotary cutting Excellent uses Quilt blocks and patchwork pieces Fat quarters and fabric strips Binding and borders Bag making and appliqué Medium garment components Paper craft with a suitable rotary blade Shared or compact sewing spaces Choose another mat for... Full-size garment pattern layouts Long yardage and extra-wide pieces Metric grid cutting Projects that need a rotating mat Cutting with art knives or utility blades Work requiring a thick heavy-duty surface Imperial grid, plain reverse: this RM-SG has a 24 x 18 inch printed grid on one side and a solid green cutting face on the other. It is not the metric-and-imperial CM series and is designed for rotary blades only. See the professional OLFA cutting system Built for precise quilting and sewing cuts The 18 x 24 inch imperial grid supports accurate rotary cutting with a ruler. A practical working size for blocks, strips, borders and everyday sewing. Double-sided construction gives measured and unprinted cutting options. OLFA's official graphic explains the self-healing surface, triple layers and double-sided use. Keep the surface smooth and the grid accurate 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.

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. A capable cutting area for everyday sewing Give your 24 inch ruler a proper place to work Choose the OLFA RM-SG when you want reliable self-healing performance, two useful cutting faces and an 18 x 24 inch format that fits comfortably into real sewing spaces.
