The process of compressing straw through a funnel to form loose coils which can be bound to form objects from chairs to baskets to bee skeps is known as lip work. One of the best materials for this work is considered to be winter wheat straw. To bind those coils, you’ll need a tough flexible material. Bramble makes an excellent binding material if one knows how to work it properly.
In the following video, Antoni Ross (www.bygonecountryskills.co.uk) demonstrates the process of selecting brambles and reducing them to the inner bark to make binding materials for a number of your upcoming projects. For this work, you’ll need a decent knife (we recommend a fix blade as opposed to a folding one) and some stout gloves. Per Antoni, you should also consider doing this work when the brambles are dormant. Here, he is working in autumn.
