Today is the deadline for churches to order their Back to Church Sunday resource packs.
The packs include 50 Back to Church Sunday invites, two A4 posters and one A3 poster to advertise their special services.
In addition, there is a "Best Bits" DVD with an introduction from the Archbishop of Canterbury, the Most Reverend Justin Welby.
In it, the Archbishop speaks of the power of a simple invitation to church.
"One to one invitation is not only the most effective way to grow the church, it's not far off the only way to grow the church," he says.
Each year, thousands of churches take part in Back to Church Sunday, a day set apart each year to give a special welcome to lapsed churchgoers.
The resource packs can be ordered from Traidcraft and cost just £25 including postage and packaging.
