Review on Clover 4031BK-B 487/W Double Tracing Wheel: Precision at its Finest by Carrie Spencer

This is metric, not imperial, so my 5/8" seam allowance is slightly wider than 5/8". However, this is the only duplicate copy wheel I could find. Kenneth King uses it in his "Jean-Ius" craft class, where he teaches you how to make a pattern from your favorite pair. Making jeans and muslin, correcting fit issues and creating the final new "clone" of the jeans. And all without having to disassemble the original pair of jeans (in other words, you don't sacrifice your favorite pair). I love this class and wanted this easy way to add a seam allowance to a pattern (pre-muslin and post-muslin patterns). Another reason I deducted a star is because unfortunately the handle is NOT ergonomic .
