Preparation and Safety Guidelines

Tools Needed
  • Fleece fabric
  • Accent fleece fabric
  • Stuffing
  • Matching thread

  • Measuring tape
Safety Guidelines
  • Always supervise your dog while wearing the costume. Remove it immediately if they show signs of distress (e.g., excessive panting, whining, trying to remove it).
  • Ensure all materials used are non-toxic and durable. Avoid anything that could easily tear, pose a choking hazard (small parts), or cause skin irritation.

Tips

  • Consider fabric choices that allow for easy bathroom breaks.
  • Use enough velcro to ensure a secure fit. Experiment with placement on your dog before sewing.
  • Draw the pattern on paper first for better accuracy before cutting into your fabric.

Common Mistakes to Avoid

1. Unevenly Cut Felt Pieces

Reason: Rushing the cutting process can lead to pieces that don't match up properly, resulting in a sloppy-looking costume.
Solution: Take your time and use sharp scissors for precise cuts, double-checking measurements before cutting.

2. Using the Wrong Adhesive

Reason: Using a glue that isn't strong enough or isn't designed for fabric can cause the costume to fall apart during wear.
Solution: Choose a strong fabric glue or adhesive specifically designed for felt and ensure it's fully dry before handling.

FAQs

What materials do I need for this no-sew dinosaur costume?
You'll primarily need an old t-shirt (preferably green or brown), felt (for spikes and eyes), elastic or ribbon, and some fabric glue or double-sided tape. Optional additions include a tail made from an old sock or felt.
My dog hates wearing clothes. How can I make sure they tolerate this costume?
Start by letting your dog get used to the t-shirt before adding the other elements. Keep the costume lightweight and comfortable, and only use gentle, pet-safe materials. Positive reinforcement with treats and praise will help them associate the costume with positive experiences. If they are very resistant, consider shorter wear times or skipping the costume altogether.
