Common Questions
Q: What size quilt blocks fit in these 18x20 bags?
A: These bags comfortably hold quilt blocks up to 16" square with room for folded edges. They're also perfect for storing multiple smaller blocks together — many quilters organize an entire block set in one bag for easy reference.
Q: Are these bags thick enough for long-term fabric storage?
A: Absolutely. At 3 mil thick, these are significantly heavier than standard 1-2 mil bags. They resist punctures, won't tear when handling bulky items, and provide excellent protection against dust and moisture for months or years of storage.
Q: Can I heat seal these poly bags?
A: Yes! LDPE poly bags seal beautifully with an impulse sealer or handheld heat sealer. You can also simply fold the top over and secure with tape or a clip for temporary storage.
