Here goes my attempt to teach you how to make a basic crochet edge around a hemstitched piece of fabric. What you will need to start:
1.
hemstitched fabric2. crochet thread - I generally use size 10 cotton thread. You can buy thread at any craft store or fabric store.
3. Crochet needle - I generally use a size 4 or 2.0MM crochet needle. Needles come in various sizes so you can choose your preference. You don't want too big of a needle or you won't be able to get it through the hemstitched holes.
Before you get started, you will want to trim around the edge of your fabric so it is about 1/4" raw edge.
Step 1: make a loop
Start by crossing the thread creating a short, loose end.

Then pull the short end of the thread through the loop to make a slip knot


Slip your needle through the loop and tug on the short end of the thread to give it a nice fit around the needle. You don't want the loop too loose or too tight...just right.

Insert the needle through a hemstitched hole

Loop the long end of the thread around the needle and pull the thread through the hole with your needle.
