Has anyone else been researching pockets to hold seasonal ordinary settings? I've had trouble finding a nonstandard library card holder large enough for the letter-size bi-fold, and although I have a lead on 5' pouches that might work, they're non adhesive and $150 per 500, not much cheaper than the plastic pouches at ~ 50¢. The recent ELCA hymnal (Evangelical Lutheran Worship) comes with a pre-installed pocket: lucky for them!
