Honchey ... It happens to me! And thus why I often have more than one thing on the go. If my brain isn't in the zone for one then I switch over to another project. At first, I hopscotched around a lot on FWS .... I'd want to sew but some of the blocks just seemed so complicated so I'd look for the easy peasy ones or ones I knew I could nab in the time I had at the moment. I'll probably do more of that with PC. And sometimes, I just want something simple and mindless to sew ... you know, goof proof! Then there are times when I just don't go near the machine. Is it burnout?
You're being productive, with all your cutting! think about how quick those blocks will sew up, when you have no decisions to make about fabrics, and the pieces are all cut and ready to go!!!!
