The following website was INCREDIBLE for helping a few of the cast members (including Thayer and his over 600 lines in Taming of the Shrew in 2014) to memorize their parts. Print out the cues and speeches for your part, then just print out your part. Have someone read the cues to you followed by you reading your lines. Tasha (Tranio in Taming of the Shrew) and her Mom did this for 1/2 hour, 4 days a week, from the time she was assigned her part...and she knew all of her lines by the end of December.
The site is called "Open Source Shakespeare." Find the appropriate play on the left, then you can either click on the character or the scene to find the appropriate lines.
After the show is over. After you have spent months getting to know the cast and crew. After you spent a week in the caucus room and on stage with these new friends. It suddenly ends. Here and here are some helpful thoughts for you from a SMASHer. She wrote it after A Midsummer Night's Dream in 2011. Everything she wrote is true!
