A beginner's guide or tool for substituting fabric in sewing projects.

Product Opportunity Analysis:

1. Identified User Need/Problem: The user, a self-described "newbie" sewer, is having trouble with fabric substitution for a cargo pants pattern. The pattern calls for a specific type of fabric (likely non-stretch or different from what the user has), and they want to use a fabric with "mechanical stretch." They're unsure if this will work and are also thinking about altering the back waist darts. This highlights a common challenge for beginners: understanding how fabric properties affect a pattern and what adjustments are needed when using a different fabric.

2. Search Phrases Indicating Opportunity:

• "Newbie questions..."
• "...I want to make. The pattern specifies X, [but I have Y]" (implied)
• The user is looking for advice on whether their chosen fabric ("mechanical stretch") can work for a pattern likely designed for a different type of fabric.
• The user is considering pattern alterations ("alter the pattern a little" regarding the waist/darts) due to fabric choice or fit.

3. Product/Service Opportunity: There's a clear opportunity for an information resource specifically designed to guide beginner to intermediate sewers through the complexities of fabric substitution and related pattern adjustments.
