There are two common ways, and both work with disposable or reusable bags.

1. With a coupler:
   • Drop the coupler base into the bag and push it to the tip.
   • Trim the bag just enough so the threaded part peeks through.
   • Place your piping tip over the base and screw on the ring until snug.
2. Without a coupler:
   • Drop the tip into the bag and push it to the end.
   • Snip the bag so only the narrow end of the tip protrudes.

Twist the bag above the filling to prevent leaks, and test with a little icing to check for gaps. A coupler can make swapping tips easier without refilling.

A small starter lineup covers most cake decorating and cookie needs:

• Round tips: Great for writing, dots, outlines, and smooth dollops.
• Open star tips: Classic swirls, rosettes, and shells with soft ridges.
• Closed star tips: More defined rosettes and borders with crisp texture.
• Petal tip: Ruffles, ribbons, and simple flower petals.
• Leaf tip: Quick leaves to finish floral designs.
• Multi-opening (grass) tip: Hair, grass, and textured effects.

Accessories like a coupler, a few piping bags (disposable and/or reusable), and basic bag ties are helpful. Many kits include numbered icing tips so it’s easier to follow tutorials. You can shop sets or individual pieces and choose pickup or delivery at checkout.

This simple setup helps reduce mess and air bubbles:

1. Fit your tip first: Add the tip (and coupler if using) before filling.
2. Make a cuff: Fold the top of the bag over your hand or a tall glass.
3. Spoon in icing: Use a spatula to add icing, filling the bag about half to two-thirds.
4. Unfold and twist: Uncuff, push icing toward the tip, twist the top, and gently “burp” out air.
5. Secure: Use a bag tie or clip and hold the bag closed with your palm.

Some decorators place smaller color bags inside a larger bag to pipe multi-color swirls. Results can vary based on icing consistency and bag thickness.

Both can work well—your choice depends on project size and cleanup preferences.

• Disposable bags: Convenient for quick projects and multiple colors. No washing, and you can trim to fit different tips.
• Reusable bags: Durable for frequent use and larger batches; many have a textured grip for control. Hand washing with mild soap is a practical option.
• Sizes: Smaller bags (10–12 inch) suit cookies and details; larger bags (14–16 inch+) are helpful for big cakes or thick buttercream.
• Compatibility: Most bags work with standard couplers and tips. Tipless bags (snip-to-size) are handy for fine outlines and lettering.

You can find multipacks and kits, then choose pickup or delivery at checkout.

Gentle cleaning and thorough drying can help tips last longer.

1. Rinse promptly: Soak tips in warm, soapy water to loosen icing.
2. Brush crevices: Use a small brush or a thin tool to clear openings, then rinse well.
3. Dry completely: Air-dry on a towel; moisture can lead to sticking or discoloration over time.
4. Reusable bags: Turn inside out, wash with mild soap, rinse, and air-dry fully before storing.
5. Storage: Keep tips in a container or organizer so sizes/markings stay visible. Couplers and rings can be stored together to avoid misplacing pieces.

If packaging indicates dishwasher-safe, top-rack placement may be suitable; when in doubt, hand washing is a careful approach.
