Svartur Interlocking Blocking Mat Set

The Svartur set includes 9 interlocking mats, a comprehensive array of 100 T-pins, 12 crochet blocking combs, and a storage bag. Individual mats measure 12 inches with a 0.47-inch thickness and feature grid lines for precise shaping.

A caution: the thinner edge profiles may flex slightly under heavy wet blocking, so use steady pressure and allow adequate drying time.

The grid lines enable precise measurement, and the mats can be assembled into a 36 by 36-inch surface or configured into various shapes.

Buying Guide: Key Considerations For Blocking Mats
What size and shape do you need? Most sets use 12×12 inch squares that can be combined into larger layouts. If your projects vary widely in size, select mats that lock together easily into 24×24, 36×36, or larger surfaces.
How thick should blocking mats be? Thicker mats (0.75 to 0.8 inches) offer more stability and pin hold, which helps with heavy blocking or longer sessions. Lighter mats are easier to transport but may flex under pressure.
Material and durability matter. EVA foam is common for its light weight and resilience. Look for heat resistance and water resistance if you plan steam blocking or wet blocking. Eco-friendly options are a plus for sustainable projects.
Included accessories can save time. Pins, storage bags, and a variety of grid markings help maintain accuracy and organization during blocking sessions. Ensure the set includes enough pins for your largest project.
Portability vs. permanence. If you block on the go or in small spaces, consider a lighter, modular set. For a home workspace, heavier mats with a storage bag offer stability and long-term use.
