I needed it to be stiff enough to stand up alone. It does great!! Not too stiff to handle, but firm enough to support the sides of the bag. Review: Perfect. - If you need a heavy weight interfacing, this works great. I’m having a hard time finding products now that Joann’s fabric has closed. This works great. ## Features - Country Of Origin : United States - Product Height : 11.5" - Product Length : 3.9" - Product Width : 0.75" ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001GA8398 | | Best Sellers Rank | #20,329 in Arts, Crafts & Sewing ( See Top 100 in Arts, Crafts & Sewing ) #55 in Sewing Interfacing | | Brand | Thermoweb | | Brand Name | Thermoweb | | Color | White | | Compatible Material | Fabric | | Customer Reviews | 4.5 out of 5 stars 881 Reviews | | Global Trade Identification Number | 00000943033387 | | Item Form | Solid | | Item Package Quantity | 1 | | Item Type Name | fusible | | Item Weight | 1.12 ounces | | Manufacturer | Notions Marketing - Drop Ship | | Material | Polyester | | Material Type | Polyester | | Model | 3338 | | Number of Pieces | 1 | | Other Special Features of the Product | Durable, Easy to Maintain, High Quality | | Part Number | 3338 | | Special Feature | Durable, Easy to Maintain, High Quality | | Specific Uses For Product | Craft, Fabric | | UPC | 096006455869 000943033387 094006455865 683203268431 095006455862 098006455863 097006455866 | | Unit Count | 1 Count | | Water Resistance Level | Water Resistant | ## Product Details - **Brand:** Thermoweb - **Color:** White - **Item Form:** Solid - **Item Package Quantity:** 1 - **Material:** Polyester ## Images ![THERMOWEB 3338 Heat'n Bond Heavy Weight Iron-On Fusible Interfacing-White 20"X36" - Image 1](https://m.media-amazon.com/images/I/81PibLTa5YL.jpg) ![THERMOWEB 3338 Heat'n Bond Heavy Weight Iron-On Fusible Interfacing-White 20"X36" - Image 2](https://m.media-amazon.com/images/I/817V7DQRBOL.jpg) ![THERMOWEB 3338 Heat'n Bond Heavy Weight Iron-On Fusible Interfacing-White 20"X36" - Image 3](https://m.media-amazon.com/images/I/71E2sYjhT2L.jpg) ![THERMOWEB 3338 Heat'n Bond Heavy Weight Iron-On Fusible Interfacing-White 20"X36" - Image 4](https://m.media-amazon.com/images/I/41XRPsV1ioL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ very heavy interfacing *by T***Y on November 10, 2013* I wanted this to make some tote bags for gifts.
