We have guests that are going to be invited to the wedding. Should they also be invited to the shower, I know that they will not be able to attend and I do not want them to feel obligated to send a gift, but I do not want to hurt anyone's feelings by not inviting them. Please let me know the proper thing to do.

You do not need to invite all the wedding guests to your shower(s). In fact, this is generally not the case, in that there are usually more wedding guests than shower guests. If you invite someone to a shower, however, they should also be invited to the wedding (except in the case of office showers).

Shower guests usually just include your maid of honor and bridesmaids (groomsmen too if men are invited), the mothers and sisters of the bride and groom, and other close relatives and friends.

Your wedding guests who you know cannot attend a shower should not feel hurt by not being invited. They will simply be happy to get invites to the wedding.
