Squimpish Boutique Blends vs. SF Blend: Which Is Better for Fly Tying?

Squimpish Boutique Blends and Steve Farrar SF Blend are both loose, pre-blended synthetic fly tying materials designed for baitfish, streamers, predator flies, and saltwater patterns.

Both combine synthetic fibers with flash and arrive ready to tie, which makes them much more directly comparable than patch-mounted Squimpish Hair.

The biggest differences come down to fiber length, blend construction, color combinations, taper, and how much control the tyer wants over the finished profile.

Boutique Blends vs. Steve Farrar SF Blend: At a Glance

The Biggest Similarity: Ready-to-Tie Blended Material

Boutique Blends and SF Blend solve a very similar problem at the vise: giving fly tyers a loose synthetic material with color and flash already incorporated.

Instead of selecting several different materials and creating a blend from scratch, both give you a ready-to-use combination that can be pulled from the package and tied directly into the fly.

What Makes Boutique Blends Different?

Squimpish Boutique Blends are custom combinations of Squimpish fibers, coordinated colors, and flash. Each blend is designed as a finished colorway rather than simply adding flash to a single fiber color.

Because the material is loose, you can easily pull apart the blend, change the amount you are using, layer it sparsely, combine it with another color, or reshape the fibers for the profile you want.

Boutique Blends typically use fibers approximately 4 to 9 inches long, making them versatile across medium-size baitfish, streamers, Hollow-style flies, and larger freshwater or saltwater patterns.

What Makes SF Blend Different?

Steve Farrar SF Blend is a loose synthetic material with fine flash already mixed throughout the fibers. It is commonly sold in lengths of around 10 inches and is widely used for large baitfish, streamers, predator flies, and saltwater patterns.

SF Blend is known for arriving as a ready-made, pre-tapered blend, which makes it convenient when you want to build a defined baitfish profile with minimal preparation.

Fiber Length and Fly Size

One of the clearest differences is working length.

Boutique Blends typically range from approximately 4 to 9 inches, which gives tyers flexibility for medium-size streamers, baitfish, and Hollow-style patterns.

SF Blend is commonly around 10 inches long, making it especially useful when the pattern calls for a longer pre-blended synthetic material.

Color and Flash

Both materials arrive with flash already incorporated, but their color approach is slightly different.

Boutique Blends are built as custom Squimpish color combinations, often using multiple coordinated shades with flash to create a specific finished baitfish or attractor profile.

SF Blend combines synthetic fibers and flash into a ready-made material designed to create translucent baitfish and streamer profiles.

Water Retention and Casting

Squimpish fibers retain little to no water, helping larger flies shed water between casts and reducing added water weight.

SF Blend is also designed to shed water well, which is one reason it has remained popular for large baitfish and saltwater patterns.

Both materials are useful choices when you want synthetic fibers that perform well in larger flies without becoming unnecessarily waterlogged.

Movement and Profile

Boutique Blends can be tied sparsely, layered, pulled apart, reshuffled, or combined with other materials to change the shape and density of the fly.

SF Blend is particularly useful when you want a pre-tapered material that quickly builds a defined baitfish silhouette with flash already distributed through the profile.

The better option comes down to how much you want to manipulate the blend versus how much you want the material to arrive already prepared for you.

Where Does Squimpish Hair Fit?

Squimpish Hair is a different format from both Boutique Blends and SF Blend. Instead of arriving as a loose pre-mixed blend, Squimpish Hair is woven onto a patch to mimic the presentation of natural bucktail.

This gives the tyer more control over how the material is built. You can blend different Squimpish Hair colors yourself, decide how much flash to add, use sparse applications, and control exactly where each layer sits within the fly.

Squimpish Hair fibers also maintain a consistent diameter from root to tip. They can be cut to virtually any desired length, reshuffled, and restacked to recreate a natural-looking taper by staggering the fiber ends.

If you want a ready-made loose blend with coordinated colors and flash, Boutique Blends are the closer Squimpish comparison to SF Blend. If you want maximum control over color, flash, fiber length, and taper, Squimpish Hair is the better fit.

Which Material Should You Use?

Choose Boutique Blends When:

• You want loose Squimpish fibers already blended with flash.
• You want custom color combinations ready to use.
• You prefer to pull apart, layer, or reshape a loose blend.
• You are tying streamers, baitfish, Hollow-style flies, or predator patterns.
• You want little to no water retention.

Choose SF Blend When:

• You want an approximately 10-inch pre-blended synthetic material.
• You prefer a pre-tapered loose blend.
• You want fine flash already distributed throughout the material.
• You are tying patterns traditionally designed around SF Blend.
• You want a ready-to-use material for larger baitfish and streamer profiles.

Choose Squimpish Hair When:

• You want a patch-mounted synthetic material.
• You want complete control over color and flash.
• You want to cut, reshuffle, and restack fibers to custom lengths.
• You want longer options, including Squimpish Hair XL.
• You prefer building your own taper and profile through sparse layering.

Can Boutique Blends and SF Blend Be Used Together?

Absolutely. Both are loose blended materials, and combining them can give fly tyers even more control over color, flash, length, and profile.

A longer SF Blend base can be combined with sparse layers of Boutique Blend to introduce additional color, flash, or texture. Boutique Blends can also be used as accent layers within a larger baitfish profile.

As with most synthetic materials, sparse applications usually give the tyer more control. Adding small amounts in layers can create depth and movement without making the fly unnecessarily bulky.

Frequently Asked Questions

Are Boutique Blends similar to SF Blend?

Yes. Both are loose, pre-blended synthetic fly tying materials with flash already incorporated. Boutique Blends use custom combinations of Squimpish fibers, coordinated colors, and flash, while SF Blend uses its own synthetic fiber and flash construction.

Which material is longer?

Boutique Blends typically range from approximately 4 to 9 inches. SF Blend is commonly sold at approximately 10 inches long.

Do Boutique Blends already contain flash?

Yes. Boutique Blends are custom loose combinations of Squimpish fibers, coordinated colors, and flash, so they arrive ready to tie.

Do Boutique Blends absorb water?

Squimpish fibers retain little to no water, which helps reduce added water weight when casting larger baitfish, streamer, and predator patterns.

Which material gives me more control over color combinations?

Boutique Blends arrive in custom Squimpish color combinations and can be pulled apart, layered, or combined with other blends. If you want complete control from individual colors upward, Squimpish Hair or Squimpish Loose Fiber gives you even more freedom to build your own combinations.

Which material is best for large baitfish flies?

Both can work well. SF Blend provides an approximately 10-inch pre-blended material, while Boutique Blends provide shorter custom Squimpish blends that can be layered or combined with other materials. For exceptionally long flies, Squimpish Hair XL provides fibers approximately 10 to 14 inches.
