This topic is all about finding or making open-ended ostomy pouch covers that can fit any ostomy bag, and understanding how to measure correctly for them. Here are some helpful insights and advice:

1. Truly "one-size-fits-all" covers are somewhat limited. The stretch in the fabric around the wafer opening can only accommodate a certain range of sizes.

2. Before buying or making a cover, it's important to measure:
- The diameter of the hole that needs to fit snugly around the wafer or barrier.
- The width and length of the pouch itself.

3. There are off-the-shelf options available. Some covers have an elasticized opening, allowing them to lie flat against the base and fit most mainstream pouch sizes.

4. DIY solutions are quite popular. They are often cheaper and allow you to customize the fabric with seasonal prints, sports teams, lace, and more. Even those who don't sew have found success with simple patterns. You can find a free step-by-step pattern at stomaatje.com.

5. If you prefer to purchase ready-made covers, there are online options with international shipping available at cancerbeglammed.com.

6. Users have noted practical benefits of using pouch covers:
- They add comfort in hot, humid climates by reducing sweat against the plastic pouch.
- They provide a psychological boost, similar to wearing attractive underwear, making the user feel good even if no one else sees it.
