I have only received 2 boxes and purchased the blocks needed from previous boxes to be able to finish the farm quilt. The boxes are a very good value, I like the fact I can get a quilt block every month and the additional projects are very good. The material from last month I really liked plus the template was one I didn’t have. I look forward to the box coming every month, when they get here I open them right away then have to share pictures with my daughter.
If you have to change the stash box subscription to quarterly my suggestion would be to keep the quilt block maybe send three blocks every quarter so it still has the quilt block. My opinion is to keep the stash box the same other than that and do the quarterly if you have to although I will miss the monthly.
Again I really like the stash box subscription and hope you keep the boxes going.
