These gift vouchers are valid for 2 years from the date of purchase and can be used to attend a mosaic course, oo buy mosaic materials, to purchase a mosaic gift or to commission a small mosaic, like a house number. 
There is no administration charge so a voucher for £50 will buy £50 of materials or course costing £50.
The recipient can contact me to book a course or buy products. 
If you are intending the voucher to be used for a course, please note that the full day course is £85 and a half day is £50. If the voucher is for less it can be used towards the full cost. 
If you buy a voucher I will contact you by email to confirm where you would like it sent and if you want the voucher personalised.
