 Foreword  
Uganda National Bureau of Standards (UNBS) is a parastatal under the Ministry of Trade , Industry and 
Cooperatives established under Cap 327 , of the Laws of Uganda , as amended .  UNBS is mandated to co -
ordinate the elaboration of standards and is  
(a) a member of International Organisation for Standardisation (ISO) and  
(b) a contact point for the WHO/FAO Codex Alimentarius Commission on Food Standards, and  
(c) the National Enquiry Point on T BT Agreement  of the World Trade Organisation (WTO).  
The work of preparing Uganda Standards is carried out through Technical Committees. A Technical 
Committee is established to deliberate on standards in a given field or area and consists of key stakeholder s 
including government, academia, consumer groups, private sector and other interested parties.  
Draft Uganda Standards adopted by the Technical Committee are widely circulated to stakeholders and the 
general public for comments. The committee reviews the comments before recommending the draft standards 
for approval and declaration as Uganda Standards by the National Standards Council.  
The committee responsible for this document is Technical Committee UNBS /TC 311-Crafts and related 
products

(Informative)  
 
Types of weaving techniques  
A.1 Techniques used to weave baskets  
Handwoven baskets may be weaved using some of the following techniques:  
A.1.1  Coiled  
A core (bundle of strands or rods) are stitched into a spiralling oval or round form.  There are many kinds of 
materials and stitch types that can be used for the core bundles or stitching.  
 
A.1.2  Twined  
Two or more flexible elements encircle a base. Pairing and waling are specific types of twining. Materials can  
vary from flexible native naturals to waxed linen, cordage, or other fibres  
 
 
A.1.3  Woven  
Rigid stakes or spokes create a warp, and more pliable materials are woven in and out to create a weft. 
Materials can be flat or round a nd either natural or human -made.  
DUS 2368 :2021

A.1.4  Plaiting  
Stakes and weavers are the same material. They are woven together in either a diagonal or horizontal/vertical 
orientation in plain or twill weaves as shown below .
