Great Price

Given the cost these products are good value for money. It would be helpful if the fabric was more accurately cut and cut in a straight line.

Partly good

Parcel arrived in time and well packaged. One item was sent incorrectly - bias binding 12mms when i ordered 25mm. Was told this would be rectified and correct product sent. That was nearly a week ago. I'm still waiting for it.
