Hang in there, it WILL all be worth it !!
In the meantime, take a break whenever you can and do some hand piecing, applique, punchneedle etc ... just to keep your Sewing Soul happy !! Or go to a friend's house and sew -
We are "still" remodeling our home - no addition, just updates - but it's ALL stressful and tiring. My sewing time has really suffered lately - but I've done some wool applique and punchneedle to help keep my sanity !! :)
