There are no 'must have' tools when it comes to hand piecing your patchwork and quilts, well aside from, you know, a needle and thread... however over time you'll find there are tools that you use again and again, that help you hand piece. I've listed my current tool box kit below, it can change over time, but these are pretty much my go-to tools.
If you’re new to hand piecing but not new to quilting you may have never considered making your patchwork by hand or consider making patchwork by hand as a crazy endeavour! Before sewing machines were invented (in the 1830’s!) how do you think vintage quilts were created… by hand.
