I adore the look of tumbling blocks. The Y seams are so intimidating. I have tried machine piecing and it doesn't work well for me (I have made about 20 quilts so I have some experience). For those of you who do hand pieced quilts, is it difficult to learn? Does it work well for tumbling blocks? I thought I could bring a few to do during lunch break at work each day and slowly build a quilt. Let me know what you think. Thanks!
