The topic at hand is about finding solutions for when you run out of ostomy barrier paste. The original poster is looking for homemade alternatives or better options, as they often find themselves without paste and have resorted to using duct tape as a temporary fix. Here are some helpful suggestions and insights shared by others:

1. Buy/stock-up strategies:
- Consider ordering paste in larger quantities and set reminders to reorder before you run out.
- Some community members offer surplus paste for sale at a reasonable price.

2. Low-cost/alternative sources:
- Alibaba offers a product called "Steadlive 60 g Skin Barrier Filler Ostomy" at a lower cost, though the quality and ease of removal are uncertain.
- In emergencies, denture cream can be used as a temporary substitute.

3. Tape & extender options instead of paste:
- Micropore tape from a pharmacy can be a better option than duct tape for securing the flange.
- Barrier extenders like "C-strip" and other strips can help hold flanges in place without the need for paste.
- Medvance Silicone Tape is recommended for its strong adhesion and skin-friendly properties.

4. Ring or seal alternatives:
- Brava Barrier Rings are praised for being cleaner and less messy, providing longer wear time than paste.
- Eakin Cohesive Rings are suggested for sealing uneven skin, though some users have experienced skin reactions and recommend trying newer, gentler brands.

5. Technique tips:
- Paste is primarily used to fill surface irregularities; if your skin is flat, you might not need it.
- Apply only a thin bead of paste, as over-application can lead to issues.
- Warming the adhesive of a 1-piece pouch with a hair dryer for a few seconds can improve bonding and might eliminate the need for paste, especially for colostomies.

6. Important cautions:
- Using duct tape or too much paste can harm the skin around the stoma.
- When trying non-brand or DIY products, proceed with caution and keep an eye on your skin's condition.
