Similar to the Chef's Mitt, the Jiffy Mitt is slightly smaller and finishes at 7-1/2" by 12". It, too, uses Bosal's die-cut batting (not included) and is considered a beginner's level design. With Bosal's batting, your oven mitt will be able to withstand temperatures up to 450 °, saving your hands from hot pots and pans. You can use scrap fabric or fat-quarters to complete this fun pattern. The Jiffy Mitt Pattern includes detailed instructions and a list of suggested materials.
