Called in at Lidl today and found some very useful spring clips at £3.99 a pack, 16 clips in all various sizes, from about 6 inch long down to 2 inch long. Us them to attach fleece etc.
They also had g-clamps that work one handed similar to mastic gun mechanism. £1.99 a pack of 2 large or 4 small. again very useful for holding fencing in place while you fix it in position.
