Slip the wire through the edges of your project and place pins along the inside of the wires to hold them in place while the project dries.
Set comes with 15 (34.5"/880mm long) straight wires (est. 15 gauge), 20 nickel-plated T-pins and blocking instructions. All wires are stainless steel and rust proof. The first time you use your blocking wires, wipe them with a soft cloth to remove manufacturing residue.
