Czech Glass Bead Shapes: SuperDuo, GemDuo, Tila and Rulla Guide
Czech glass beads come from the Bohemian glass region of the Czech Republic, an area producing glass beads continuously since the 1500s. The shapes covered below are all relatively recent inventions — most within the last 20 years — but they sit on top of centuries of glass-pressing craft.
The five Czech shapes that anchor most modern patterns
- SuperDuo & MiniDuo — 2-hole ovals. The most-used Czech bead in modern patterns.
- GemDuo — 8 x 5 mm flat-faceted 2-hole. Reads as a decorative statement bead.
- Tila family — flat square 2-hole beads (technically Miyuki, used Czech-style).
- Rulla — cylindrical 2-hole bead that lies flat. Cuff-bracelet friendly.
- CzechMates & Par Puca — coordinated multi-shape systems for pattern-rich designs.

01 · The fundamentals
Why two holes?
Single-hole beads can be strung or woven, but they always have one structural weakness: they pivot freely on the thread, so the work can curl, twist or sag. A second hole gives the bead a second anchor point, which lets a row sit flat and lets the designer build patterns where one bead's edges align precisely with the next bead's edges.
That is the difference between traditional Victorian beadwork and a modern contemporary pattern. Most of the shapes below are 2-hole. A few of the more advanced shapes (Par Puca's Arcos, for example) are 3-hole.
02 · Core 2-hole shapes
SuperDuo and MiniDuo
The SuperDuo is the most-used Czech 2-hole bead in the world. It is an oval, slightly faceted bead measuring approximately 5 x 2.5 mm with two holes running parallel along the length. The MiniDuo is its smaller sibling at 4 x 2.5 mm.
If you can only learn one 2-hole shape to start, this is the one. Almost every introductory 2-hole pattern uses SuperDuos, and the colour range is enormous — opaque, transparent, lustred, metallic, matt and bronze finishes are all standard.
Pair with: Miyuki seed beads in size 11/0 or 15/0, fire-polished rounds in 3 mm or 4 mm, and CzechMates Bricks for contrast.
03 · Statement shapes
GemDuo
The GemDuo is a Matubo design — an 8 x 5 mm flat-faceted 2-hole bead that reads much larger and more decorative than a SuperDuo. The flat front face catches light differently, so a row of GemDuos has a stained-glass quality.
Patterns built around GemDuos tend to be statement pieces — pendants, focal points and wider cuffs — rather than subtle work.
Pair with: SuperDuos and MiniDuos to fill the spaces between GemDuo flat faces, plus 15/0 Miyuki seed beads to lock the pattern together at the edges.
GemDuo's flat front face means it photographs like a small jewel rather than a bead. If your pattern needs a focal point that the eye lands on first, the GemDuo is the cleanest single-shape way to provide it. Combine with 11/0 Miyuki for the seed-bead-grade detail in between.
04 · Flat tile shapes
Tila, Half-Tila and Quarter-Tila
Strictly, Tilas are Japanese-made by Miyuki, not Czech — but they are used so interchangeably with Czech 2-hole shapes in modern patterns that they belong in the same conversation. They are flat, square tile-shaped beads with two parallel holes:
| Shape | Dimensions | Thickness |
|---|---|---|
| Tila | 5 x 5 mm | 1.9 mm |
| Half-Tila | 5 x 2.5 mm | 1.9 mm |
| Quarter-Tila | 5 x 1.2 mm | 1.9 mm |
Tilas create a brickwork effect when stitched in rows, which suits geometric patterns and Art Deco designs. The flat surfaces also mean colour reads strongly, so Tilas are popular in pieces that need bold colour blocks.
"Tila holes are right at the edge of the bead, so they can have sharp inner edges. Use thread protectors — small rubber sleeves over your needle stop — at any point where you turn the thread back through the same bead."
— Critical for Tila peyote work. Skipping this risks fraying or snapping your thread mid-row.
05 · Cuff-builder shapes
Rulla
The Rulla is a 5 x 3 mm cylindrical 2-hole bead. It lies absolutely flat in a row, which makes it ideal for cuff bracelets where you want a solid, structured band rather than a draped one.
Rullas come in a more limited colour range than SuperDuos but in some lovely metallic and matte finishes that suit autumnal palettes.
06 · Coordinated system
CzechMates: shapes designed to work together
CzechMates is not a single shape but a coordinated family of shapes designed to work together. The maker (Starman) sizes every CzechMates shape so the holes line up across shapes when you stitch them in combination.
If you are buying CzechMates, buy them by the pattern's shape list rather than improvising. The system rewards using its components together.
The coordinated shape family
07 · French-designed shapes
Par Puca: architectural Czech beads
Par Puca beads are designed in France by Pucabeads but pressed in the Czech Republic. They are sold by their named shapes:
- Kheops — 6 mm triangular 2-hole.
- Arcos — 5 x 10 mm curved 3-hole.
- Minos — 2.5 x 3 mm tiny 2-hole.
- Amos — 5 x 8 mm pear-shaped 2-hole.
- Ava — 10 x 4 mm curved 3-hole, similar idea to Arcos but with a different curve.
- Ios — 2.5 x 5 mm thin 2-hole.
Par Puca patterns are some of the most architecturally interesting in contemporary bead weaving. The shapes lend themselves to geometric, lattice-like designs.
08 · The constant
Fire-polished rounds
Fire-polished round beads are not new shapes — they are the classic Czech crystal alternative, available from 2 mm to 8 mm and in every finish from clear to AB to opaque to lustred. Almost every 2-hole pattern uses fire-polished rounds in 3 mm or 4 mm to fill the spaces and add sparkle.
Stock a 3 mm and a 4 mm in a few core finishes (jet, crystal AB, bronze, gold) and you will be ready for most patterns.
Drop 4 mm fire-polished rounds between every pair of SuperDuos and the pattern instantly gains sparkle and lift. The faceted surface catches light at angles the matt or pressed shapes cannot, which is why almost every published 2-hole pattern from the last decade lists them.
09 · First steps
How to choose your first set of Czech bead shapes
If you are starting from zero, the most useful starter set is below. With these six components, you can read the materials list of a substantial number of published 2-hole patterns and start picking apart how the shapes lock together.
Bronze, jet or gold. The backbone of your starter projects.
Provides the statement face that catches light against the SuperDuo base.
Matching tone to lock the pattern at the edges.
Crystal AB or similar — the sparkle in the gaps.
The standard pairing for SuperDuos, Tilas and CzechMates work.

FAQ
Common questions about Czech glass shapes
What is the difference between SuperDuo and MiniDuo?
Both are 2-hole ovals from the same family. SuperDuo is approximately 5 x 2.5 mm; MiniDuo is the smaller 4 x 2.5 mm. The hole spacing is different, so they are not interchangeable inside a pattern — check which one your pattern specifies before ordering.
Are Tila beads Czech or Japanese?
Tilas are Japanese-made by Miyuki, but they are designed and used as 2-hole pattern beads in the same way as Czech multi-hole shapes. Most contemporary pattern designers treat them as part of the Czech-style toolkit, which is why they appear in the same conversations.
Do I need a special thread for Czech glass beads?
Czech glass holes vary by shape, so always test before committing to a full project. As a general rule, SuperDuos, Tilas and Rullas take a size 10 or 12 beading needle with Fireline or Superlon. Tilas have flat sides and can have sharp edges around the hole, so use thread protectors at any point you turn back through the same bead.
Can I substitute one CzechMates shape for another?
Not freely. The CzechMates system is engineered so the hole positions line up across shapes when stitched together. Swapping a Brick for a Tile changes the row width and breaks the alignment. Stick to the pattern's shape list, or design your own piece around a specific shape mix from the start.
Are Par Puca and CzechMates compatible?
Sometimes. Par Puca Minos beads pair particularly well with CzechMates Bricks because they share similar small-bead spacing. Par Puca Kheops and Arcos are more idiosyncratic shapes and tend to anchor their own patterns. If a pattern calls for both systems, follow the bead list exactly.
In summary
The vocabulary is large — but learnable
Start with SuperDuos and fire-polished rounds, add a single accent shape (GemDuo, Tila or Rulla) to your starter kit, and you will be able to read the components list of almost any 2-hole pattern in the world. Once that becomes second nature, the CzechMates and Par Puca systems open up — and at that point you stop reading the components list at all and start designing your own.
